Powder Magazine at Snibston Colliery

The Powder Magazine at Snibston Colliery is a purpose-built explosives store, part of the mid-20th century development of the colliery, completed between 1947 and 1951.

Constructed from red brick with plain concrete dressings, it features a bitumen-coated flat roof. The building has a single-cell, rectangular plan designed with compartments for the separate storage of explosives.

Located immediately north of Winding House No 2, the single-storey Powder Magazine has single doors at each end of the front (north) elevation, along with seven small window openings with glass block glazing beneath a continuous lintel band between the doorways. The other elevations do not have any openings.

Inside, the space is divided longitudinally by a continuous counter from which explosives were dispensed. The two doorways were arranged for an 'In' and 'Out' passage, allowing explosives to depart from one end of the building. Behind the counter on the south side, there are compartments set into an internal wall, separating the dispensing area from the explosives storage area. At the east end, beyond the counter, is a small separate room with an open-fronted storage unit containing numbered individual compartments, along with another storage unit against the east end wall. The Powder Magazine was designed to securely store explosives and detonators, facilitating the distribution of materials and the receipt and disposal of unused explosives.
