Watergate of St Ann's Fort and associated wall

The Watergate of St Ann's Fort and its associated wall were built between 1570 and 1571, with alterations and repairs made in the 17th, 18th, 19th, and 20th centuries, including some infilling. The structure is primarily made of red brick, with some stone repairs and infill.

This linear structure serves as the wall and gate to St Ann’s Fort. On the south face towards the west end of the wall, there are two depressed arches and part of a third, all blocked with 19th-century brick. At the western end of these arches, there is a springer for a brick arch that extends south, suggesting the presence of an inner vaulted chamber or carriageway. Continuing east from the arches is a length of contemporary brick wall that has been much repaired and altered. On the southern side of the eastern end of this wall, there is a plaque that reads G.B. & Co 1875. Just beyond the plaque, the wall turns at a right angle and runs south, forming the east wall of an open courtyard. Various blocked openings and scars indicate where former buildings once stood, and the 1887 Ordnance Survey map shows a malthouse in this location.

On the north side of the wall, at the western end, the structure is built out and contains two barrel-vaulted passageways that would have emerged through the blocked arches on the south side. The north side also features other brick arches and openings, many marked by wooden or concrete lintels, most of which have been infilled. The early brickwork is interspersed with repairs and alterations from the 18th, 19th, and 20th centuries, reflecting the ongoing changes in the use of the fort wall.
