Largely late 13th to early 14th century, but with parts of the fabric considerably earlier. Granite and sandstone rubble with ashlar dressings. West tower and spire, nave with clerestory and two aisles, chancel. In the north wall, there is one Decorated window and one small round arched opening, late Saxon or early Norman, with the arched head cut from a single stone. Its sill is part of a band which is continuous across the north wall, and which would have linked with the fragment on the east wall, suggesting that the east wall was partially rebuilt when its window was inserted and that the main fabric of the chancel is late Saxon or early Norman.
