Among these are a wonderful 12th-century chancel arch and several small 12th-century windows.
The 12th-century chancel is built of stone, but the 18th-century nave and west tower are made of brick. The interior furnishings are mostly Georgian, with a range of box pews a west gallery, and a nicely carved pulpit.
Surrounding the church are the partial remains of a large polygonal churchyard, now largely buried, but the boundaries are laid out with hedges and stone walls.
St James' is no longer used for regular worship and is in the care of the Churches Conservation Trust.
