The cross is possibly built using limestone salvaged from the ruined part of Malmesbury Abbey, which stood just across the market square. The cross was renovated in c.1800 by the Earl of Suffolk, and repaired in 1909–1912 and again in 1949–1950. The central shaft is octagonal in plan and stands on a low plinth. On each face is a moulded four-centre open arch, and there are two entrances facing south west and north east. A large lantern above the roof is supported by cyma-moulded, arch-braced roll top flying buttresses, with figures of the saints and the Crucifixion set in niches beneath attached finials. The roof has an ogee cap with crockets and finials. The interior comprises a central octagonal shaft with attached columns and a low bench.
