Lamyatt lies within the triangle formed by Castle Cary (2 miles SE), Bruton and Evercreech, Somerset (3 miles to the N). The name means ‘lamb gate’, referring to the gap in the horseshoe of hills surrounding Evercreech (Watts, 2004). The village is on Lower Lias limestone, with Creech Hill to the E rising to Fuller’s Earth limestone. The church lies at 118m altitude 800m W of Lamyatt Beacon, in its own conch-like combe, 700m NE of the village centre, accompanied by its farm (‘Lamyatt Farm’) and associated buildings. The church is predominantly Perpendicular in date, but has a Romanesque font.

In 1086 Lamyatt belonged to Glastonbury Abbey, as part of Ditcheat Manor (about 3.5km W). Nigel the doctor held 5.5 hides in Lamyatt from the Abbey.

Lamyatt Beacon, about half a mile E of the church, is the location of a Roman temple, indicating that the site has been occupied for a very long time.
