The early 13th century nave is now partly a lobby and vestry and retains its original windows. In the latter part of that same century a chancel was added which is longer and wider than the nave. It also retains its original windows. This period, architecturally is known as early english. In the early part of the 14th century material from the ruined castle nearby was probably used to build a massive west tower, also wider than the nave, but this was destroyed by the Welsh during the revolt led by Owain Glyndwr in 1403 and its base together with the original east wall (now the west wall of the nave) is all that remains.

The spectacular timber beamed roof of the chancel is 15th century and has received some recent careful restorative attention along with other parts of the church. The porch and bell turret are of c1711 and the pulpit carving is of roughly the same time. The font is thought to be 14th century.
