Holy Trinity Church is located at the centre of Llandow Village and is possibly of pre-Conquest origin, although the earliest fabric, including a pillar piscina, is Norman. There is also a Norman font.

The chancel was restored in 1712 by the rector of Llandow, and in 1889 the whole church was restored and the South porch was added. The roof of the nave and chancel were replaced by a scissor-beam roof, buttressing was added to the nave and chancel, and the pews, pulpit and much of the fenestration was replaced.
