Terrain Archaeology undertook a programme of archaeological observations and recording during trenching associated with the creation of a new sewer at Max Gate, Alington Avenue, Dorchester in July 2013. A number of archaeological features were identified. These included a possible Late Iron Age field boundary ditch that may be part of a more extensive field system previously identified in excavations for the Dorchester by-pass, just to the west and north west of Max Gate, and again further to the west at Alington Avenue. A number of Roman features were identified, including a small pit containing Roman pottery, animal bone, brick and tile dating to c. AD70-110, and a ditch aligned NNE-SSW of 2nd century AD date. A Late Roman inhumation grave, probably of later 4th century date, was disturbed and some human skull fragments exposed. An L-shaped iron coffin bracket with a tri-lobed decorative terminal, an iron coffin nail and a lathe-turned Kimmeridge shale spindle whorl were recorded from this grave. An adjacent feature just to the south may be a second grave, but this could not be confirmed.
