Marksbury is a small village in Somerset sited near the Chew valley, about 5.5 miles SW of Bath and 13 miles NE of Wells. The meaning of the place-name (‘boundary-fort’) suggests potentially significant history (Costen, 1983). S of the Avon Valley, E of the Chew Valley and W of Newton Brook Valley, Marksbury is in a historically active area and nowadays part of a favoured, prosperous district either side of the Avon. The bedrock on which the village rests is the Lower Lias known as ‘Blue Lias’. There is a quarry marked on nineteenth-century OS mapping immediately W of the village. One of the site photos, taken from the neighbouring parish of Farmborough, gives a view across the relatively flat land of Marksbury Plain to the church tower and beyond to the hills of Winsbury and Stantonbury. The original settlement lies offset below and to the NW of the A39, which is a long-established route along the high ground.
The church of St Peter therefore would seem originally to have occupied an almost solitary commanding position (at 124m above OD) on the high ground of the ridge, isolated except for its farm close-by on its SW side. The church consists of W tower, nave, N porch and chancel. The church is of late 12thc origin, but mainly dates to the 15thc, and was extensively restored in 1875. The only Romanesque feature present is a 12thc font.
