The 15th century Gileston Church lies on the site of the earlier church, and is romantically situated next to Gileston Manor, in the grounds in which it lies. There is a chancel, nave, south porch and tower with battlements with one bell.
The four-step churchyard cross was destroyed by Cromwell's soldiers as being idolatrous (somehow only that at St Donat's escaped vandalism across the southern vale) but was restored in 1900. A piece of ornamental stone from the corner of the church was re-carved and placed on top of the broken shaft.
There are four massive stone steps to the cross base. A sundial on a plinth dates from 1927 and is inscribed 'I summon up remembrance of things past'.
