As suggested by the place-name, Hinton Blewett is on high ground — specifically, at an altitude of about 150m above OD on the N side of the upper Chew valley. Its local stream, the Cam Brook, rises nearby and runs NE parallel to the small village on its SE side. The bedrock here is Triassic Blue/White Lias above Mercia Mudstone (formerly called Keuper Marl) — the Lias outcrops forming a large ring around coal measures. The village is only reachable by lanes: its remoteness paradoxical for a location within 15kms of Bristol city centre but typical of the settlements in this hilly area between the Avon and Mendip. Access to the outer world is by the secondary road linking West Harptree (A368) with Chewton Mendip (A39) or by the A37 (at Temple Cloud via Cameley, 3kms E).

The church is on the N side of the village centre and consists of a chancel, nave with N aisle and S porch and a W tower. Construction is of squared and coursed rubble in the nave and porch and random rubble in the tower, all with ashlar dressings. The church is largely of the 13thc with the aisle added in 1553 and the tower rebuilt in the 1780s. There was a restoration in 1928.

Hinton Blewitt was assessed at 8 hides in 1066. In 1086 it was held by Ralph from William d'Eu except for half a hide that was held by Hugh from William d'Eu. In addition to the ploughland there wa woodland a league long and a furlong broad, 60 acres of meadow and a mill.

A much plainer font in the same cushion capital form is to be found at Hardington Bampfylde.
