Sufficient survives of the 12thc church to indicate that it had a N, and probably a S aisle also. The present building consists of a 13thc chancel, and 16thc N and S aisles at the E end of the nave which were extended W in the 13thc when a W tower was added. The S porch is 16thc, relocated in 1877, the N aisle of c.1832 was rebuilt in 1877, and the W tower was also rebuilt in 1877.

The settlement was valued at £12 in the Domesday Book, when it was held jointly by St Peter's Abbey, Abbotsbury and Hugh son of Gwip's wife. By 1291 the church was appropriated, unusually the rector was specified as the pittancer, rather than the Abbey as corporate rector. The rectory was valued at £17.

Glynne noted two arches to the blocked N arcade on his visit to ‘Portisham’ in 1830, but to judge from the fabric around, he can have seen only the one surviving today.
