Sutton Montis lies 6 miles NW of Sherborne and close to Cadbury Castle. The church of Holy Trinity lies on Church Hill to the N of the main village settlement. It has Saxon origins, but the earliest surviving work is 12thc. It is built of Cary stone, roughly squared and coursed, with Doulting stone dressings and consists of a W tower, nave and chancel. The chancel arch is early 12thc.

In 1066 the estate was held by Bondi. In 1086 it was held by the Count of Mortain, with Drogo as sub-tenant.

The chancel arch is a fine feature and the detail of the stepped chevron is unusual, creating a rich effect. It is not clear why the hoodmould would have been tooled back. Perhaps there was a need for a flat surface for a royal coat of arms in the early modern period. One would have expected it to be chamfered and quirked.

The S capital carries the beautiful anthemion design rare in Somerset in the fieldworker's experience but also to be found in the E capital of the S door at Ashill, twenty miles away. See St Mary, Ashill, Somerset - CRSBI
