ROCHESTER EAST GATE, 1969*
By A. C. HARRISON, B.A., F.S.A.
INTRODUCTION
IN 1969 it was learned that the area of nos. 108 -122 High Street
(N.G.R. TQ 744684) was to be cleared of buildings and converted into
a car park. As the city wall was known to run through the site and it
was thought probable that part of the East Gate itself might be found,
an excavation was carried out between 11th August and 9th September
by permission of the Rochester City Council, the landowners. Much
help from the Town Clerk and City Surveyor of Rochester is gratefully
acknowledged. As the time available for the excavation was limited,
it was necessary to begin when the demohtion of the premises was less
than half completed and, in this connection, I must express my
appreciation of the co-operation afforded by the demohtion contractors,
Messrs. Bennett Bros., of Gillingham. Financial assistance was provided
by the then Mimstry of Pubhc Building and Works (now the Department
of the Environment). The work of the excavation was carried out
by members of the Lower Medway Archseological Research Group,
by the pupils of Sir Joseph Williamson's Mathematical School and the
Rochester Grammar School for Girls, whose hard work made this
excavation possible.
The following year the demohtion of the Mathematical School on
the opposite side of the High Street made possible a limited amount
of investigation, here also again by Mnd permission of the City authorities,
and the results of these excavations are included in this paper.
THE EXCAVATIONS
1. Western Area
(a) Roman. As the central area had been destroyed, archseologically
speaking, by a deep modern basement, and as the eastern part
of the site was not yet cleared, excavation was begun at the west end,
where it was thought remains of early habitation might be expected.
This hope was disappointed as, except for an area of flint and ragstone
cobbling found in Trench 6 at a depth of 5 ft. 6 in. to the south of the
cellar of no. 110, no trace of any sort of building was found. It is
perhaps possible to interpret this cobbling as a yard belonging to a

building facing the High Street and destroyed by the digging of the
cellar, but, if so, it must have been one of hght construction as no
trace of foundations was found.
The earhest features were the two small gullies, R.10 and R.ll, and
the ditch, R.12, into which the latter gully ran. These all contained
pottery of the first century A.D. and were presumably for drainage.
During the second century the whole of the area was extensively used
for rubbish disposal and pits dug for this purpose were numerous. Over
the southern part of the area these pits were sealed at an average depth
of 4 ft. 6 in. from the present surface by a layer of yellow subsoil of a
thickness which varied from 15 in. to 3 in. and which became thinner
towards the north, disappearing at a point about 65 ft. from the High
Street. This was clearly the result of an extensive excavation nearby
and is interpreted as trampled up-cast either from the Phase I ditch,
which hes about 80 ft. to the south, or from the construction of the
Phase II wall and wall-bank which are even closer. The latter hypothesis
is preferred in view of the pottery from this layer which included colourcoated,
Rhenish, red-ware and flanged bowls suggestive of a thirdcentury
date. This dating is supported by a coin of Tetricus (270-273),
from the same layer. This might be an indication that the Phase II
wall was built rather later than hitherto supposed,1 but this evidence
is not conclusive because the layer is a thin one and the coin not
therefore strictly sealed. The later Roman period is represented only
by a layer of brown 'top-soil' containing a mixture of third- and fourthcentury
sherds and by a pit (R.13) of third-century date. It would
./ppear, therefore, that the south-eastern corner of the Roman town
remained unoccupied, possibly because it was thought desirable to
keep a strip immediately inside the walls clear of houses.
(b) Medieval. The main feature, the precinct wall of the Priory,
was found, as expected, running roughly parallel to the High Street,
at a depth of 3 ft. 3 in. from the present surface in Trench 5. This wall,
the construction of which was authorized by Edward III in 1345, had
previously been traced in 1887,2 at a point opposite the choir of the
Cathedral, when some 85 ft. of it were uncovered. There it was recorded
as being 15 ft. from the High Street but here its northern edge was
52 ft. from the pavement. Only the foundation remained, composed
of chalk and rubble in a soft light-brown mortar and this was 5 ft. wide
and 4 ft. 8 in. deep on the north side, rather less on the south. Fortunately,
it was possible also to locate the junction of this wall with the
east wall of the city, which occurred at a point 56 ft. from the edge of
the present pavement in Trench 8. Here the foundation was at a considerably
higher level, owing to the Roman wall-bank which had not

been cut through, and had been much damaged, but it was possible to
trace its south edge for 6 ft. to the west. It was thus possible to plot
the course ofthis wall over the whole of the area (Fig. 1).
About 30 ft. to the south of the precinct wall in the area which,
from the wording of the 1345 charter, is known to have formed part
of the monks' garden, was a hne of substantial post-holes of early
medieval date (Trench 1). In front of these, and, very possibly, to be
connected with them, were two kilns for the manufacture of clay loomweights,
one of which, Kiln A, clearly represented an unsuccessful
firing as the batch of about 40 weights was in situ (Fig. 2, and PI. I).
This kiln was intact, but Kiln B in Trench 3 had been empty when it
was partially destroyed by a later pit. As it would appear that this is
the first time a site for manufacturing these weights has been recorded,
it has seemed worthwhile to give a fairly detailed description.3 The
design was extremely simple, consisting merely of a trench 7 ft. by
3 ft. 6 in. and 2 ft. deep cut into the soil and lined with clay. This lining
was quite thin in A but in B, which had been used and re-lined at least
three times, it was several inches thick and incorporated four 'waster'
weights as well as some very useful pottery. The trench had then
been filled with a mixture of fuel and weights and fired from the south
end. It is not quite certain whether the trenches were roofed over,
though numerous fragments of daub recovered from the area suggest
that this was so. Alternatively, it is possible that the trenches were
left open until the fire was well alight and were then banked up with
clay to slow down combustion as in primitive pottery manufacture.
A date of c. 1100 A.D. is suggested for the kilns (see Fig. 14 and p. 144,
below). Six rubbish-pits (Ml-6), some of considerable size, were found
in the area.
2. Eastern Area
(a) Roman. The opportunity was taken to out a long section
(Trench 7) through the earth-works inside the Roman city wall, parts
of which survive here to a considerable height as a result of having
been incorporated in the seventeenth-century building now demohshed.
While the general picture (Fig. 3, PI. II) was much the same as from
previous excavations inside the wall4 it was more complete and there
3 Two rows of Saxon loom-weights, numbering 30 and 32 respectively and
nearly 10 ft. in length, were found at Grimstone End, Pakenham, Suffolk, and
were interpreted by the excavator as being piled ready for firing rather than as
having fallen from a loom, because in his view the width was too great for a shuttle
to have been used. This argument, however, is invalid as shuttles were not usually
employed with the warp-weighted loom, and it seems more likely that these
weights did in fact comprise a wide loom. (See N. Smedley, G. M. Knooker,
S. E. West and B. J. W. Brown, 'Excavations at Grimstone End, Pakenham',
Proc. Suffolk Inst. Arch., xxvi (1954), 198-9, pi. xxiv.)

were some additional points of interest. The profile of the Phase I
rampart was here nearly complete except in front where it had been
cut away to make room for the building of the wall. It comprised a
sloping bank of subsoil with the same revetment of laminated clay in
front which has been observed elsewhere,5 6 ft. 3 in. high at its highest
remaining point and 23 ft. 6 in. in length. Owing to its having been cut
away in front there were no post-holes remaining from the palisade
which it seems reasonable to assume was there. This rampart had been
enclosed in the bank of earth piled up inside the wall after it was
completed. Neither the original height nor the length of this wall-bank
could be determmed, but from the angle of the tip-lines its length
cannot have been less than 40 feet. Pottery from both the wall-bank
and the Phase I rampart was scarce but the contents of the two rubbish
pits (R.17 and R.18) sealed beneath the latter confirm the suggested
late second-century date for Phase I. The wall, as elsewhere, stood on a

concrete raft, 15 in. thick, which rested upon a foundation trench
2 ft. 1 in. deep filled with layers of rammed flints. The wall itself
sloped at a slight angle as far as its first offset, which occurred at
3 ft. 9 in., and for a further 9 in. above it. At this point, there was
clear evidence that the wall had coUapsed and been rebuilt. After a
thick layer of mortar, the character of the masonry changed, the joints
being no longer finished flush with the stones, and the wall-face became
vertical. Furthermore, as shown in the section, the wall-bank had had
to be dug back in order to make the stump of the damaged wall accessible
for repairs. This horizontal break in the wall was traced for 66 ft.
to the north and may well have extended to the East Gate. The cause
of the collapse is conjectural, but it seems possible that it was due to
the wall being set too close to the edge of the Phase I ditch. The few
scraps of pottery recovered from the fill of the repair-trench were
suggestive of the first half of the third century, but the date may well
have been later.
Outside the waU the Phase I ditch was sectioned in three places.
Of these the two nearest the Gate had been truncated by the cellar of
no. 122 High Street but, the one furthest south in Trench 9, gave a
complete profile of the west side of the ditch (Fig. 4 and PI. Ill) which
had originally been approximately 17 ft. wide and 8 ft. deep. As elsewhere,
6 this had been back-filled with material cut away from the Phase I
rampart. There was, however, a deposit of silt nearly 2 ft. in depth at
the bottom and pottery from this (Fig. 4) also suggests that the ditch
was open during the last years of the second century or the early years
of the third. It should be mentioned that the ditch continued to the
north under the existing pavement and that no trace was found of the
Roman East Gate or roadway.
The outer face of the Roman city wall was exposed in Trench 9.
Although part of the facing had been robbed and replaced by brickwork,
enough remained to show that the lowest courses consisted of
blocks of ragstone much more massive than the squared ashlar used
higher up (PI. IV). This fact is important for the interpretation of the
stretch of the east wall on the north side of the High Street which is
discussed below (p. 128).
(b) Medieval. In the south-east corner of Trench 9 the edge of the
1225 A.D. ditch7 was found cutting into the filling of the Roman ditch
mentioned above. The section-drawing (Fig. 4) shows this relationship.
The sloping surface of the ditch had been cut into shallow steps, presumably
to facihtate the removal of spoil during its construction. In
the cellar of no. 122 High Street (Fig. 5) the earhest architectural
feature was a foundation of rammed chalk projecting nearly at right-

angles from the line of the city wall. This was 2 ft. thick, 5 ft. 6 in. wide
and extended for more than 21 ft. to the east. It did not produce any
dating evidence but is thought to have been the foundation of an early
medieval Gate House of rectangular shape. Against this had been
abutted a very solidly constructed masonry foundation of flint and
ragstone set in a pale yellow mortar (PI. V). Its shape was rather more
than a semi-circle, its width 4 ft. 9 in. with a projection 2 ft. 8 in. wide
1 ft. below its top surface and its total depth was 5 ft. 6 in. The
projecting flange, which was certainly of the same build as the rest,
is a curious feature in that there would seem to have been a change of
plan while building was in progress. Starting 1 ft. below the top surface
at the north-west extremity, it was level for several feet on the outside
of the curve but then sloped away rapidly and disappeared just inside
the smaller cellar. On the inside curve the slope began almost immediately
and the flange terminated at about the same point. Yet,
both inside and outside, a trench had been dug wide enough to accommodate
the flange, a trench subsequently filled with clean red gravel.
This foundation, taken in conjunction with the similar curved foundation
described by Canon Livett8 and, until recently, still partly visible on
the opposite side of the High Street (PI. VI), clearly formed part of the
southern drum-tower of the later medieval East Gate, which is shown
with a pointed arch-way between tall flanking towers in Wilham
Smith's drawing of Rochester, dated 1588.9 There was a number of
medieval rubbish-pits (M7-M13) in the vicinity of the Gate and one
of these (M7) was cut by the curved foundation. The pottery from this
nit, therefore, which is of thirteenth-century date (see p. 150, below)
provides a terminus a quo for the building of the tower.
On the small undisturbed area in the centre of the tower foundation
were the remains of a hearth which had clearly been used for iron
smelting, as quantities of iron slag were recovered from its ashes. A coin
of Honorius sealed beneath it makes it improbable that it was Roman,
and it must be earlier than the construction of the drum-tower as it
was cut by the foundation-trench, so an early medieval date seems
probable.

Roman. As the Phase I ditch had been seen to continue to the
north under the present pavement, it was thought worthwhile to try
to trace it on the other side of the High Street, where it was found to
continue to the north for 18 ft. from the building-line before terminating
(Fig. 5). The silt of the ditch produced late second-century pottery.
The building of the Mathematical School had destroyed all stratification

except for the lowest 5 ft. of the ditch itself, and to investigate the
possibihty that the end of the ditch marked the position of an entrance
through the Phase I defences a small excavation, Trench 10, was made
inside the wall (Fig. 5). The Phase I rampart, however, was found to
continue unbroken, as did the Phase II wall, though here reduced to its
foundation courses. (The implications of this are discussed below.)
Sealed beneath the rampart was a layer of burnt material with a
considerable quantity of iron slag and late second-century pottery.
The City Wall. From the East Gate to the drum-tower at the
north-east angle the wall of the city is well preserved. All that is now
visible is of one period of building, and it is thought to be of fourteenthcentury
date, but it clearly foUows the line of the Roman wall now
revealed to the south of the High Street. A curve in the wall near to
the corner indicates that its Roman predecessor ended in a rounded
corner similar to the south-eastern corner visible in Eagle Court. Below
ground, it has been the subject of a number of small excavations
(Fig. 6 A, B, C, D, E, F) between 1960 and 1971, all of which have
presented the same general picture. Trench F (Fig. 7) which was dug
in I96010 is worth illustrating as typifying the others, though in the
trenches nearest to the East Gate all stratification had been destroyed.
Clean brick-earth was reached at a depth of 10 ft., overlaid by a patch
of cobbling, the western margin of which ran roughly parallel with the
wall and about 12 in. from it. Pottery from the make up ofthis cobbling
is Roman, dating from the latter part of the second century, and it
was covered by a layer of sterile green clay, containing small pieces of
carbonized twigs. Through this clay had been dug the foundation-trench
of the earliest wall, 2 ft. 4 in. in depth and filled with layers of rammed
flints set in a blue-green clay, similar to that used to revet the Phase I
rampart. A spread of mortar droppings and small pieces of ragstone
ran up to the foot of the wall, overlaying the clay. The wall was faced
with blocks of roughly squared ragstone set in a hard brown mortar. The
lowest course was offset by 6 in. to form a plinth 8 in. deep and three
courses remained above this (22 in. in all). The whole structure was
tilted outwards indicating that the wall had collapsed at this point.
A layer of dark earth containing pottery of thirteenth- or early
fourteenth-century date lay against this earliest wall and, presumably,
marked the ground level from which rebuilding took place, though no
mortar-scatter had survived, presumably because, when the ditch
was filled in in the seventeenth century, its edge was dug away. (This
suggestion is strengthened by the fact that the mortar of the wall
showed weathering for 4 ft. below the present ground level, indicating
that the hp of the medieval ditch reached this point.) Above this layer
10 Trenches A and C were dug in collaboration with Mr. 0. R. Plight, B.A.,
of. Arch. Cant., lxxvi (1961), Ixxiii.

there were no stratified deposits. On the stump of the earher wall had
been built 6 ft. of unfaced and rough rubble walling with a shght batter.
The material was largely rubble from the collapsed wall with the hard
brown mortar still adhering to it and contrasting strongly with the
soft white mortar in which it was reset. The faced medieval wall rested
on this rubble walling and was set back 6 in. from it. Trench E was
similar in all respects except that there were mortar-droppings adhering
to the stump of the first wall. In Trench D, the Roman levels had been
entirely dug away, but six courses survived to a total height of 4 ft. 6 in.,
with only one course of the rubble-walling required before the
faced wall above. In Cuttings A, B and C there was no stratification,
and the rubble walling was absent, the faced wall resting directly upon
the top of the first wall, here surviving for seven courses. The identification
of the earher wall with the Roman city wall would have seemed
obvious but for one fact. The masonry seemed to differ in character from
that of the south-eastern corner, long recognized as Roman: the stones
were larger and more irregular and the coursing less exact. However, the
discovery in 1971 that the lower courses of the south-eastern wall
were of the same character (PI. IV) has removed the difficulty, and it
is now evident that the whole of the medieval wall between the East
Gate and the north-eastern corner stands upon the lower courses of the
Roman wall with the drum-tower taking the place of the original
rounded corner.
The medieval wall is 7 ft. wide and 20 ft. high to the foot-walk, with
the external facing of the coursed ragstone and dressed flint intact.
The put-log holes are well preserved at intervals of 12 ft. horizontally
and 4 ft. verticaUy. The internal facing, however, is destroyed or m odern.
A considerable length of the crenellated parapet remains with seven of
the original embrasures and one side and the sill of an eighth. The
parapet is 5 ft. 6 in. high and 2 ft. thick, with a triangular-sectioned
coping 1 ft. 6 in. high of two courses of ragstone ashlar; the embrasures,
spaced at intervals of 12 ft., are 2 ft. wide with ashlar quoins and ashlar
sills, chamfered on both edges, 3 ft. above the foot-walk.
The drum-tower at the north-east angle is of one build with the
wall and, in its present state, of the same height, the foot-walk being
continued around the top of the tower; originally, it was at least one
storey higher (Fig. 8, and PL VII). Entry into the tower was by a
doorway on the south-western side and the fact that this doorway is
only a few inches below the present ground level suggests that there
was an internal wall-bank. The doorway has a two-centred arch,
rebated internally and with a double chamfer externally (PL VIII).
The left-hand jamb is original, but the right-hand has been patched.
To the right of the doorway is a small square-headed window, blocked
within the last few years. Through the doorway is a small vaulted
