A watching brief was undertaken in July 2006 for the construction of two bungalows on land at 31 Hadrian Close. The property sits within the area of the former Romano-British town and port of Abonae, which dates from 1st–4th centuries AD. Excavation of foundation trenches revealed a series of Pennant sandstone and Lias limestone walls from former buildings, a large rubbish pit, postholes, small gullies and a metalled road surface on a north west-south east orientation.
Three small trenches were also excavated for water tanks. Within these trenches were the remains of more stone surfaces and another building wall. Set within one surface were a re-used quern stone and a possible large whetstone.
Finds retrieved from the watching brief consist of Samian ware bowls and cups from Gaul (Former France and Belgium), mortaria (vessels for grinding and processing of foodstuffs) from the N. Gaul (Brittany area) and amphorae (storage vessels which carried olive oil, garum [a fish sauce] or wine) from Spain. Local storage vessels were also collected which came from Dorset (Black Burnished Ware), the Severn Valley (Severn Valley Ware) and the Bristol region.
