In 1980 and 1981 The Canterbury Archaeological Trust excavated on adjacent sites at 69a Stour Street and Adelaide Place. The sitecodes were CB/RIV and CB/RV.
The excavation revealed a number of Roman features and deposits and a road, aligned roughly NW/SW had been metalled many times and was probably Roman Watling Street. Extending over both sites was a well-defined constrcution horizon associated with the laying out of a huge colonnaded enclosure, possibly belonging to a temple. Occupaton continued well into the 5th century, a remarkable find was a group burial dating to this time found on CB/RV. However similar late Roman or Saxon levels were not found on CB/RIV. Instead a thick deposit of possible agricultural soil was found, a black-brown loam containing post-Conquest material.

The robbing of the Roman walls is believed to have taken place in 12th century. Medieval pits were seen on both sites, though in a much greater quantity on CB/RIV. The earliest pits seem to have been dug at the same time as the robbing of the portico. On the Stour Street frontage the pits were sealed by the clay floor of a small timber-framed building with two associated hearths/ovens and a barrel lined well. The building was of 13th century date.
A later flint wall bisected the site, it was associated with a single-phase clay floor and it is possibly from a previously unrecorded and undocumented large stone house. Two small timber framed hall houses were found positioned on either side of the stone wall.
