The village of Thorne St Margaret stands on rising ground on the S bank of the River Tone, 7miles W of Taunton and less than 2 miles from the Devon border. The church is in the centre of the village, and consists of a 2-bay chancel with a S vestry and organ room, a nave with S aisle and S porch, and a W tower, all of red sandstone random rubble. The tower is 15thc and the remainder 19thc, but there are 12thc carved stones reused on the interior of the S doorway, and a 12thc font.
