Monkton Farleigh is a village and civil parish in west Wiltshire, England, on high ground 3 miles (5 km) northwest of Bradford-on-Avon, and a similar distance east of the city of Bath.

[2] The Roman road from Silchester to Bath, and later earthworks which may be part of Wansdyke,[3] run east–west and form the northern boundary of the modern parish.

[8][9] The civil parish has 34 listed buildings, including:[10] Woodland at Inwood is a biological Site of Special Scientific Interest.

[20] The easily hewn Bath stone, a form of limestone, had created a number of large, horizontal, and relatively dry quarries around Corsham.

This was attached by a 1.25 miles (2.01 km) tunnel built by The Cementation Company, descending at a rate of 1:8.5 to the Central Ammunition Depot, housed in the former mine workings.

[21] The narrow gauge trucks would descend from the platform to the tunnel, where a heavy-duty conveyor belt would carry the ammunition directly to the appropriate storage gallery.

The conveyor belt, and the original cable-way used as a temporary installation while the tunnel was being built, ran continuously for 30 days in the run-up to D-Day.

Today the north end of the tunnel is sealed by a concrete and rubble installation, while the former mine/CAD is used for secure commercial document storage.
