Natural deposits 
Fig. 4. Stratigraphic sequence diagram 
and 4 illustrates its stratigraphic separation from 
the rest of the buildings: its footing trench [1020] 
and foundation (1019) are sealed by layer (1016) 
which form the base of a ‘make-up’ sequence 
through which walls (1000) and (1027) etc are cut. 
Phase 3. 
Traces of the lower of two limestone pavements 
were encountered in the main excavation and in 
Trenches B, C and D, stratigraphically above Phase 
2 deposits and partially truncated by the main walls 
of the West Barn (Phase 4). The pavement 
comprised a well-defined, cambered, 200mm deep 
course of limestone ‘pitchstones’ (1003, 1008, 1010, 
and 1055) bedded on two layers of compacted 
limestone rubble (1004/1022 and _ 1005/1016) 
together approximately 200mm thick. Three areas 
of paving were revealed: an E-W pavement (1055) 
at the west end of the barn, approximately 4.5m 
wide; a N-S pavement (1010, 1008, 205) 2.5m wide 
and bounded on both sides by well-formed stone 
gutters (1011 and 1009) in the excavations on the 
south side of the barn; and fragments of a N-S 
pavement (1003) against the east end of the north 
side of the barn. The latter two were bounded by 
spreads of flat-laid limestone rubble paving (1014), 
the spatial extent of which lay outside the 
excavations. The northern extent of (1003) had 
been truncated by later disturbances (see below), 
but the compacted limestone rubble base extended 
as a continuous and well-defined layer (1036) from 
the north face of the barn foundation along the 
entire length of Trenches C and D and the western 
part of B. Stratigraphically level with the lower 
pavement was a series of stone conduits (1030, 
1042, 1058) revealed in Trenches C and in the 
French drain at the west end of the West Barn. 
These conduits were formed of two skins of 
undressed limestone slabs approximately 300mm 
apart capped by a single course of similarly 
undressed limestone slabs, set into the compacted 
limestone rubble base (1036) of the lower 
pavement. Though visible only in short lengths, 
two are discernible: running N-S (1030/1042) 
through Trenches C and B, and running E-W 
(1058) from the west end of the West Barn. The 
eastern extent of (1058) was not identified: it did 
not exist within the reduced interior of the West 
Barn, and the French drain excavations along the 
east and north foundations were not deep enough to 
encounter it. 
Phase 4. Main walls 
The limestone pavements were cut by the footings 
of the south (1007), west (0004), north ( 1000) and 
east (1006) walls of the West Barn, and in places the 
lower course of the wall proper (above the 
foundation) lay directly on pavement setts. The
