Marcross (Welsh: Marcroes) is a small village in the rural community of St Donats in the Vale of Glamorgan, south Wales.

[1] The church retains many of its Norman features, including a large font,[2] an excellent chancel arch and a pair of intriguing corbels who guard the south doorway.

[3] Holy Trinity was restored at the turn of the twentieth century,[4] with work including a new roof, pulpit and altar, but the whole building still retains traces of the whitewash that once covered many local churches.

[4] Since the church appears to be in need of repairs, particularly after a series of spring storms in 2016, a village fund raiser was held at the Horseshoe Inn in May 2016, to help with the costs of the work.

[7] Today, the lighthouse's automatic operation is monitored by Trinity House's control centre at Harwich in Essex.
