Peasedown St John is a large village and civil parish in Somerset, England, standing on a hilltop roughly 5 miles (8 km) south-southwest of the city of Bath, and 2 miles (3 km) north-east of the town of Radstock at the foot of the Mendip Hills. Peasedown used to be a coal mining village, and after the last of the mines shut in the 1970s it became a dormitory village for Bath, Trowbridge and to a lesser extent Bristol. Its size was increased by substantial housing developments in the 1960s, 1970s and late 1990s, making it one of the largest villages in Somerset.
