It has some reused moulded stones in the jambs and is set within a moulded C16 brick frame for a shorter window.
It has offset buttresses, three pairs of C13-style lancets and a C13-style door with a pointed head and continuously chamfered opening.
Plain, probably C14 altar recess in chancel N wall.
There are also three C16 recesses in the N, S and W walls of the tower.
C18 royal arms.
Polygonal C19 wineglass pulpit.
There was a C13 lancet
apparently a C14 E window with reticulated tracery.
The tower was added in the late C16, and there was further work in the C18 when dormers removed in the C19 were added to the nave, buttresses were added and other repairs were carried out including refacing and rendering the N and E walls of the chancel.
