One of three earth bulwarks built on the seaward side of Great Yarmouth in 1539. This was sited on the East side of Market Gate, near the present Britannia Pier. (PastScape ref. Kent 1988)

Gatehouse Comments

Several 'bulwarkes of earth' built in 1539 along beach from mouth of the Yare (St Nicholas's Gat) to the town. One of these may have been the base for the South Mount, a rectangular mound erected in 1590 at the South-west corner of the town wall, between the South Gate and the River Yare, to cover the southern approach to the town and the boom over the river. It mounted 7 heavy guns on its summit. This was removed in C19. There seems to be some confusion in some records between the South Mount and the New Mount
