Powder Magazine and walls

Powder magazine and flanking walls, constructed by John Shaw in 1828.

MATERIALS: ashlar walls with slate roof and timber doors.

PLAN: a single cell, rounded lozenge shaped building with a high flanking blast wall which extends about 5-6m beyond the magazine at either end.

EXTERIOR: the magazine is a single storey structure, constructed of large stone ashlar blocks, supporting a slate roof with swept hipped ends and parapet gutter. The building lacks fenestration but two single wooden panelled doors are located on the curved ends. A small buttress has been built within the north-east angle between magazine and flanking wall. Scarring at the south-east angle suggests a matching buttress was once present there. The extending walls are downward stepped to either side of the magazine.
