Hoy, Lyness, South West Of Ore Farm, Former Munitions Depot

Ministry of Supply, circa 1938. 4 rectangular-plan former ammunition stores. The buildings comprise an inner shuttered concrete structure with buttressed outer concrete baffle wall and an earthen mound to baffle walls. Large concrete curbs extend from the store openings. Low gradient pitched roof.

Double steel doors and small ventilators in each gable end face large concrete kerbs extending from the entrances. On each side of the kerb are small concrete platforms where shells and fuses would be transferred from vehicles into and out of the store. In front of the steel doors are metal barred gates. The roof has a very low pitch with a central row of ventilators.

The interiors to the stores were seen in 2013 and are accessed from two doorways in the main elevation gable end. Concrete piers support the roof over the various rooms. The metal rolling racks remain where ammunition would be conveyed in wooden trays. A number of steel doors remain in the stores. The original room layout is intact.
