Crow South East Of Higher Biscovillack Farmhouse (Farmhouse Not Included)

Crow, located southeast of Higher Biscovillack Farmhouse, is likely a cool store or possibly a pigsty, dating from the 18th century. It is constructed from granite and blue elvan rubble, with a chamber built into a rubble-faced bank and a blocked doorway at the front. The interior is not accessible, but it is noted that the chamber is roofed with granite lintels for at least the first two feet. This building is a very rare surviving example of a primitive building type that is unique to Cornwall. There are other listed examples in Mabe and Penwith in the west of the county, but this is one of only two known examples in the china clay district of Cornwall. The other example, located at Penhale, may be buried under earth or could have been destroyed when the associated farmstead was leveled.
