In 1978 The Canterbury Archaeological Trust excavated upon the site of the present 12-16 Marlowe Arcade in advance of development.
Area MII - A number of similarly post holes and beam trenches indicated the presence of a building (R1). A number of ovens associated with the structure were also found as well as further ovens and furnaces to the south of a pebble driveway. R1 is believed to have been built around 70/80AD and had been deliberately destroyed c.100/110 AD.
Also within area MII parts of five rooms were located forming the south east corner of the St Margaret's Street Roman Baths complex, labelled building R3. R3 is thought to have been founded in the late first/early second century AD and a Roman road surface was recorded probably relating to the the rebuilding of this area.

Building R4, a portico, was also investigated within area MII and surrounded the baths. It is thought that the Baths and Portico were built at the same time as a single project. The portico is believed to have been demolished around 300-320. The portico enclosed a pebbled surface palaestra within which was found evidence for a watertank.
