.AN IRON AGE .AND ROMANO-BRITISH SITE
AT STONE CASTLE QUARRY, GREENHITHE*
By A. P. DETSIOAS, M.A., F.S.A.
!.NTRODUOTION
For O.S.
A brief trial excavation was carried out late in the autumn of 1960
following the discovery of a rubbish pit containing Romano-British
pottery at Stone Castle Quarry, Greenhithe; and, as further evidence
of occupation came to light in later quarrying operations, a full-scale
rescue excavation was undertaken the following year on behalf of the
then Ministry of Works, by permission of the landowners, Messrs.
Associated Portland Cement Manufacturers Limited, and the kind
assistance of their local manager, Mr. A. J. Thoma.s.1
My many thanks are due to the many volunteers who helped in
this excavation and, in particular, to Messrs. R. G. Foord, L. A.
Griffith, T. Hetherington, G. K. Horner and J. Vickers for their sustained
support throughout the course of the work. I am also greatly
indebted to Mr. D. F. Allen, B.A., F.B.A., F.S.A., for identifying the
coins; Mr. I. J. Bissett, for drawing some of the pottery; Miss D.
Charlesworth, M.A., F.S.A., for reporting on the glass; Mr. R. G.
Foord, for photographing some of the finds; Mrs. K. F. Hartley, B.A.,
for reporting on the mortaria; my former colleague, Mr. A. J. Hewitt,
B.A., for carrying out a preliminary survey of the site in very adverse
weather conditions; Miss J. E. King, for identifying the bones; my
brother-in-law, Dr. R. P. S. Jefferies, B.A., Ph.D., F.G.S., for the
original information of the site and his notes on its geology; and Mr.
E. R. Swain, for his drawings of the small finds.
TRE SrTE
The site lies approximately one mile south-east of the hamlet of
Stone and some 300 yards north of Watling Street (A2); it is situated,
at about 100 feet above O.D., directly on Upper Chalk, but within
150 yards of a Coombe Rock deposit2 (N.G.R. TQ/583732; O.S. 6-inch
Sheet TQ 57 SE).

GREENHITHE REPORT
In the course of quarrying, the mechanical excavator exposed a
deposit contafaing the fossilized remains of cold-phase Pleistocene
mammals, including mammoth;2 this discovery was eventually notified
to the British Museum (Natural History) and, on inspection of the
site, it was observed that the mechanical excavator had also cut through
what appeared to be a pit filled with domestic refuse and pottery
(Pit 1). Some of this pottery was recovered and, with the assistance of
Mr. L. A. Griffith, an attempt was made to cut a regular section through
this deposit exposed in the quarry face. At the same time as this work
was taking place, the landowners began the mechanical stripping of
the topsoil from the area immediately to the south of this pit in order
to extend quarrying in that direction. Watch was kept on that area,
and it soon became clear that a much longer season of excavation
would have to be carried out so as to secure as much of the evidence
as possible before it was finally destroyed by quarrying.
THE Exe.A. VATION
The main area of the excavation was bounded to north and west
by the quarry face, to south by a small copse and to east by a slight
drop in ground level, probably the result of the silting of a small stream
(Fig. 1, inset map). The topsoil, which was nowhere deeper than 6 in.
at most, consisted mainly of rough scrub, roots and bushes, and was
stripped by means of a bulldozer whose primary concern was to clear
the area for further quarrying rather than to prepare the ground for
an archreological investigation; as a result,· some of the underlying
chalk was removed as well and with it all evidence of post-holes that
might have survived within the enclosures. In fact, it is likely that
most of the evidence that was secured would have been quite lost
in the course of bulldozing but for the fact that the pits, gullies, etc.,
had been cut deeper into the chalk than the bulldozer penetration;
however, enough evidence was salvaged to establish that this part of
the site-for it is practically certain that quarrying has destroyed
much other evidence of settlement to north and west of the excavated
area-was occupied during the Iron Age, and then from the late-first
century .A..D. into the third century, and probably later.
In brief, a number of rectilinear ditches have been traced as far
as possible and of these two. can be shown to be pre-Roman, two
ditched enclosures with associated storage pits and an isolated hearth
which afforded ample evidence of lron Age date have been investigated,
and a fairly large quarry pit with three associated ovens were exposed
and fully recorded. These features are described below within their
respective periods.

GREENHITHE REPORT
(A) IRON AGE
Ditch 3 was situated almost on the very edge of the slope to the
east of the site and has suffered very badly in the course of bulldozing.
It was traced for some 60 ft. on a south to north-east direction; its
surviving width was about 2 ft. and its depth 1 ft. This ditch was
found filled with rammed chalk and clay; there was neither any silt at
the bottom nor any stratified material. It was impossible to trace its
course further than shown on the site plan (Fig. 1), but it must date
to a time soon after the abandonment of Enclosure B as the ditch cuts
through it; furthermore, the slight deviation from its rectilinear course
at the south end of the site must have been necessary in order to
avoid Pit 4 which, still in existence if not in use, it would have otherwise
bisected. Its purpose, like that of the other ditch of this period,
can only be conjectured; it may have served as a boundary ditch.
Ditch 2 antedates both Ditch 1 and the larger of the two enclosures
as it is cut by both of these features; it is less wide and deep than
Ditch 2, quite rectilinear and would seem to have formed the boundary
of a near-rectangular enclosure. It was found to be 1 ft. wide and had
survived to a depth of about 4-6 in.; it was traced for some 40 ft. to
west from its south-east corner and 156 ft. to north ·where it was lost
in a pipe of soft clay near the edge of the quarry face. A gap of some
11 ft. in this longer alignment may have been an entrance into the
enclosed area; if this entrance were placed centrally, then the north-east
corner of the enclosure would have been some 11 ft. further north of
its last known point and a little beyond the edge of the quarry face,
making a probable total length of some 167 ft. The length of the south
side of this enclosure cannot be computed. No dating material was
found anywhere in the compact clay and chalk filling of this ditch,
though it is certain that it constitutes one of the earliest features on
the site.
Hearth. Among several areas of discoloration, showing in the subsoil
after the mechanical removal of the topsoil, was a roughly circular
hole in the chalk; this was first thought to be a natural clay pipe, but
a section cut across it from north to south showed that it was not a
natural deposit. The chalk had been removed to a depth of about 3 ft.
and back-filled with a layer of red loam similar to such material found
re-deposited inside the quarry pit at a later date; whether this hole had
originally been used as a storage pit could not be ascertained, though
it might be thought that its presence outside either of the two enclosures
would preclude this use. Whatever its original function, it had a small
hearth (about 3 ft. in diameter) placed on the red loam and dating to
the same period as the smaller of the two enclosures; animal bones,
much soot and charcoal as well as some pottery were recovered in
such small quantities that, unless much more of this pottery was lost
138
GREENHITHE REPORT
in the bulldozing, it seems likely that this hearth was not in use over
a very long period of time.
Enclosure A. This is the smaller of two enclosures found at the site
and the one most likely to have contained a hut. It is very nearly
circular, with a diameter of about 54 ft., and was enclosed by a shallow
gully which was rarely more than 6 in. deep and cut into the subsoil;
no post-holes were found anywhere in the perimeter of this gully.
The enclosure was entered through a gap (5 ft. 6 in. wide) in its gully
facing towards the north-east; it is worth noting that this entrance
corresponds to the gap in Ditch 2, which may suggest that the enclosure
and the ditch were contemporary before the latter was superseded by
Enclosure B. Two storage pits were found within Enclosure A, the
larger and deeper of the two to the south-west of the entrance and the
smaller to the south and immediately inside the gully. In spite of a
systematic search of the whole enclosed area, no traces were found of
any post-holes at all. If a small hut had been contained within the ditch.
its location must have been to the south-west and behind Pit 2, but
positive evidence for this was totally lacking; if, on the other hand, the
whole of the enclosure was one hut, with the gully serving as an open
drain collecting rain-water from the roof of the hut, then one would
expect to find the post-holes for the timber framework of the hut
either in the gully itself or not very far from its inner lip-once again
such positive evidence was entirely wanting. The second alternative
that this enclosure was one single hut seems preferable as, in this case,
both storage pits would be under the cover of the hut's roof; alternatively,
if a smaller hut had been sited beyond the pits, it could be
argued that they were protected against the weather by means of
independent roofs, which seems unnecessary. Conjectural though this
must be, there was ample evidence to show how the wall and roof of
the hut were built and weather-proofed. Posts would have been set at
regular intervals and the spaces between each post filled with interwoven
wattles and such light timber; finally, the whole structure
would have been rendered waterproof by an overall application of cob,
a thick coating of puddled challr and clay. The evidence for this is
quite secure in that many fragments of cob, clearly showing the
imprints of the wattles o n which it had been applied, survived the
collapse of the hut {and the attention of the bulldozer!) inside Pit 3;
none of this material {Plate II) was recovered elsewhere on the site.
It could be argued that the cob fragments constitute the remains
of the roof of the storage pit only, but there is no evidence to suggest
that the hut itself was not lilcewise protected, and it seems reasonable
to suspect it; if the cob afforded sufficient protection for the grain
stored within the pit, why might it not have served to protect the
inhabitants of the hut as wem
139
GREENHITHE REPORT
Pit 2 (Fig. 1), the larger of the two storage pits, had been out through
the chalk to a depth of a little more than 6 ft. and was slightly more than
7 ft. in diameter; it was found filled with an accumulation of debris
layers, consisting mainly of chalk (Fig. 2, Section E-F), except for
about 2 ft. from the surface which contained a filling of charcoal, ashes
and domestic refuse. This deposit was the first surface indication leading
to the discovery of the pit after the stripping of the topsoil; the pottery
it contained was badly burnt after breakage, and it would seem beyond
doubt that, after the pit had ceased to be used as a grain store, it was
filled in and used as a rubbish pit for the disposal of material from the
hearths on the site. Some of the pottery recovered in this deposit is
of the same forms and fabrics as sherds recovered in the ashes of the
isolated hearth found outside the enclosures.
Pit 3 (Fig. 1) was much smaller and shallower than Pit 2; its diameter
was only 5 ft., its surviving depth barely 2 ft. 6 in. Though most
of its filling had been removed by the later cutting of the subsequent
Ditch 1, it had been filled mainly with a deposit of fragments of cob,
ashes, charcoal and rubbish which was practically identical with that
found at the upper levels of Pit 2; the pottery found in Pit 3 is of the
same forms and fabrics as that recovered from Pit 2, and it would follow
that both these pits were filled in at the same time. The sides of this
smaller pit had been made waterproof by the application of a coating of
yellow sandy clay against the chalk sides of the pit; this would not only
have been particularly desirable because of the proximity of the open
gully outside it, but could also indicate that parched grain may have
been stored loose in this pit rather than inside some sort of container or
lining which is likely to have been the case within the unrendered
sides of Pit 2.
Enclosure B. This is the larger of the two enclosures exposed on the
site, and the one least explored; the ground both to west, east and north
of the area where its gully was trenched either slopes sharply and the
bulldozer removed the evidence or, on more level ground, the shallowness
of the gully and the stripping of the topsoil had the same result.
However, the diameter of this enclosure can be computed at about
138 ft.; the enclosing gully was at 1 ft. 6 in. rather wider than that
around Enclosure A, and generally deeper, with a maximum depth of
about 1 ft. in parts. This gully was found filled in with a mixture of
rammed chalk and clay and contained very little stratified material,
except for most of one vessel (Fig. 5, no. 34) and a few other sherds.
Pit 4 would have been contained inside Enclosure B and had a
diameter of about 4 ft. and a depth of 1 ft. 6 in., though some of this
depth had been lost in the bulldozing down the sharp slope of the
ground; its filling consisted mainly of chalk and ashes as well as flints,
and the pottery in this deposit, some of .:which conjoins with other
