Abstract:		 A watching brief was carried on an excavation to facilitate the installation of a new manhole chamber. The excavation was located in the south-west corner of the Great Cloisters within Westminster Abbey. 3.1 Natural sand was encountered at the base of the trench at heights between 2.87m OD and 2.92m OD and, with the exceptions of the medieval walls [10] and [11] to the west and south respectively, appeared to be relatively untruncated. The principal archaeological features encountered were medieval walls which may all have been a corner of the same structure, possibly a colonnade, although one wall does also have the potential to be a foundation for one the buttresses that currently form part of the Great Cloisters. Further features were also uncovered of a later, post-medieval date including a fragment of a brick floor, and the pipes and wall foundations relating to an 18th century toilet block. There was also a medieval or post-medieval temporary mortar floor surface. Despite the impact of a modern concrete inspection chamber, the archaeological remains within the trench were remarkably well preserved and the medieval walls have been left in situ.
