Roughly oval embanked enclosure, in sloping pasture field, adjacent to Colts Hall with associated linear banks, ditches and trackways. The enclosure measures approximately 130m x 85m and encloses an area of about 1 ha (2.5 acres). Limited excavation in 1984 showed that the surrounding ditch was c.2.8m wide and 1.3m deep. The trenches also produced sherds of Thetford- type ware and C12-C14 medieval pottery, with small amounts of PMed pottery. The manorial history suggests that Colts Hall was the site of the estate of Roger de St Germain, a tenant of Richard Fitz-Gilbert of Clare, in 1086. This enclosure could therefore be a manorial compound or ringwork associated with the St Germain family. (Suffolk HER)
