Stonework

The older parts of the church have dressings of skerry, which was widely used for rubble wall material. It is very common in the Trent Valley and was probably collected from the fields or shallow pits.

The spire has blue lias limestone from the lower Jurassic period which has been used as a decorative feature found in many Nottinghamshire churches.

Lincolnshire limestone probably quarried at Ancaster has been used for window and door mouldings. This Jurassic middle lias stone is hard and oolitic, and suitable for carving.
