Description

Trellech Grange Church is a Victorian building, with the exception of the south door, which is late medieval and dates from the 17th century. The south door features a pointed chamfered arch and a Victorian door made of diagonal oak planking with strap hinges. To the right of the door, there is a two-light Decorated style window with trefoil headed lights. The east gable window is similar, but it has a trefoil above the two lights. The north wall contains two single light trefoil headed windows, along with another in the east gable. The steeply pitched bellcote on the west gable holds a single bell and is topped with a cross. The exterior of the church has remained unchanged since 1861.

The church is set within a small rectangular churchyard that features mainly Victorian headstones, the oldest of which dates back to 1830.

Inside, the church is a plastered and ceiled single cell with a nine bay Victorian waggon roof that has moulded ribs. There is a large cranked tie-beam that appears to be from the 17th century, suggesting it may date the roof, which is hidden above the ceiling. The furnishings, including benches and the pulpit, are all Victorian, except for the font, which is likely medieval but has been extensively re-cut. The lighting, heating, and altar were added in the 1950s.
