Bronze Age houses and Iron Age pits

Excavations at Castleroan 1 E3909 revealed a prehistoric settlement site, in the form of two Bronze Age houses and an associated group of post-holes, pits and stake-holes. Structure A was defined by two rings of posts, pits and slot trenches, the inner ring was concentric with the outer. It dated to the Middle Bronze Age. The internal diameter of the house was 7 m and it enclosed an internal area of 32 m 2. The external diameter was 9.5m and it enclosed an area of 65 m 2. The entrance faced east and measured 2 m. Structure B was located 6 m to the south of Structure A and was dated to the Late Bronze Age. The structure was defined by two incomplete rings of posts. The inner ring comprised six posts and two substantial slot trenches formed the entrance. The entrance was 1.5 m in width and faced north-east. The outer ring was concentric with the inner and was also incomplete. It was defined by a ring of nine posts. The diameter of the house was estimated at 7 m. The interior of the structure enclosed an area of 30 m 2 and the entire structure enclosed an area of 40 m 2. A small lithic assemblage recorded at the site was dated to the Late Neolithic/Early Bronze Age (Beaker period) and three sherds of Beaker pottery were recorded. Two Iron Age dates were returned from a pit within Structure A and from a pit located to the north-east of Structure A.
