This circular ditch marks the position of a round house pits, while a later Belgic ditch cuts straight across being excavated on the Ashville Trading Estate, whole site. Abingdon. Round the outside were numerous storage carriageway along the river provides the opportunities. Three main sites have so far been tackled.
The first was excavated by Tim Tatton Brown in 1973, before the Department of Urban Archaeology was formally established.

Here there were abundant traces of both the Roman and the medieval wharves. The Roman wharf was a very fine box frame structure, but the first medieval structure of the 13th century was rather crude and had mostly been robbed away. The short stretch that did survive showed that the wharf had been botched up from the side of an old boat, which made it all the more interesting, for it provided Peter Marsden and the ship archaeologists with another example of a medieval boat. In the 14th century this was replaced by a rather more elegant wharf, much of which still survived in its waterlogged condition.
