An archaeological evaluation was carried out on the site of the former Thomas Wolsey Special School at 642 Old Norwich Road, Ipswich, in advance of a residential development. A total of thirteen trenches were excavated, all of which exposed a natural subsoil of yellow silty clay at depths of at least 0.5m below the present ground surface. A small pit, containing two sherds of Late Iron Age pottery, was identified in one trench.
In a second trench, the remains of three subterranean concrete structures, interpreted as Second World War air-raid shelters, were exposed. Two of these had been virtually destroyed whilst the third was near complete although the roof had been removed and the interior filled with concrete.
