In the northern part of Site B, a series of post-holes (F18, F21-F25, F78-F81) appeared to form a post-ring 8.37m in diameter. This post-ring may be part of a ‘round house’. Dating evidence from associated post-holes consists of Late Bronze Age to Early Iron age pottery. The possible round-house could therefore be either Bronze Age or Early Iron Age in date. The latter is indicated, given the large assemblage of Early Iron Age pottery (c.800-600 BC) that was recovered from a shallow feature immediately adjacent to the round house. For comparison, the Middle Iron Age round house excavated on Garrison Alienated Land Area 2 in 2003 (MCC2868), had an outer post-ring 9.2m in diameter, and an outer gully (missing from the Site B example) which was 11.2m in diameter. The slightly smaller size of the Site B round house and the lack of an outer post-ring is more consistent with a Late Bronze Age date or Early Iron Age date for this structure.

The focus for the Late Bronze Age/Early Iron Age activity was the potential round house, which fits the general pattern of Late Bronze Age/Early Iron Age houses, which tend to have a single post-ring and had not yet developed the double post-ring style of buildings typical of the Iron Age.

The apparently isolated position of this Late Bronze Age to Early Iron Age house is of interest in relation to the Iron Age round house excavated on Garrison Alienated Land Area 2 in 2003 (MCC2868). The Area 2 round house is thought to represent an isolated Iron Age settlement pre-dating the construction of the oppidum. Although prehistoric pottery has been recovered from a number of locations within the Garrison, this Bronze Age round house on Area 2 (south) can be considered as another pre-oppidum occupation site.<1>
