Castletown Drill Hall, Main Street, Castletown

Castletown Drill Hall was constructed in 1892, with alterations made by Sinclair Macdonald in 1901 and by Sinclair Macdonald and Son in 1936. It is a 2-storey, 5-bay, approximately rectangular-plan former drill hall, and designed in a Scots Baronial style and is currently in use as a community hall with flats, 2015. In accordance with Section 1 (4A) of the Planning (Listed Buildings and Conservation Areas) (Scotland) Act 1997 the following are excluded from the listing: the southeast extension built in 1996.

Castletown Drill Hall is built of squared rubble, probably from the local Castlehill quarry, with ashlar dressings which are partly polished and partly stugged. The principal (southwest) elevation has a crowstepped central gabled bay with a wallhead chimney stack and the outer bays have drum towers with bellcast conical roofs with distinctive fishscale slates and iron finials (the finial to the right tower is a weathervane). There is a cill band which in the central bay rises over a recess, where a plaque (now missing) was located, and around the downpipes and there is an eaves course. There is a mix of 2 and 4-pane glazing in timber sash and case windows, a roof of grey slates and corniced chimney stacks with yellow clay cans.

There are low boundary walls to the west and east sides of the site with decorative iron railings and corner piers with squat pyramidal capstones.

The interior, which was seen in 2015, retains some late 19th century interior details including deeply moulded cornices in the hallway and in the drill hall. There is timber boarding to the hall and a low viewing gallery is still in place but is now glazed.
