St Martin's is not a particularly exciting church building. Built in 1762-3 by J. Warner of Caistor using medieval masonry, externally it is plain, pedestrian, but pleasant. Inside its white painted interior with apsidal east end, is sparse, forlorn and filthy. Sadly all the eighteenth century furnishings, except the bird bath font, were removed in a restoration of 1888.
Access: The church is kept open during daylight hours. There is plenty of roadside parking.
