Battered walls with round-headed door openings now blocked up. Ashlar entrance comprising Doric-style pilasters with carved caps, copings and impost course having recessed square-headed opening with inset round-headed arch having brick quadripartite vault to interior. Attached multiple-bay single-storey block to south having rendered parapet. Ashlar limestone walls with limestone plinth course. Round-headed window openings having limestone sills and replacement uPVC windows. Round-headed openings having replacement overlights over metal doors.

Designed by Charles Vallancey, this site is a notable example of star shaped forts favoured by the military in the eighteenth century. Called after the then Lord Lieutenant, the Earl of Westmoreland, the first regular garrison arrived in 1806. In 1810, the Arsenal was moved from Kinsale to Spike. The walls are particularly well-built with finely cut ashlar blocks. The site retains its dry ditch, which adds context to the site.
