Extract

In 1964 Chester suffered one of its worst archaeological catastrophes when extensive and well-preserved elements of the intramural fortress thermae were exposed and then destroyed within the brief space of a few months in order to facilitate the construction of an underground service bay for a new shopping precinct. Although some archaeological examination of the site was conducted before redevelopment works commenced, this was restricted by circumstances to those areas free of standing buildings. This effectively limited investigations to the area beyond and to the east of the thermae, where barrack accommodation sufficient to house a cohort occupied the corner insula in the sinistrai half of the praetentura (FIG. 1). Over the remainder of this enormous site, no facility for formal excavation was given as construction work by the contractor was timed to begin immediately following demolition of existing buildings. Although, in the event, the contractor did re-arrange his programme of works on several occasions to allow some time for archaeological investigation, and intercession by the Ancient Monuments Inspectorate won several weeks stay of execution for one part of the baths complex, most of the affected sections of the thermae were recorded merely in the form of observations made during mass mechanical excavation by the contractor.
