Camborne's parish church is dedicated to St Martin and St Meriadoc: it is entirely of granite, of 15th century date, but incorporating earlier structural features, including a Norman chevron stone in the west wall of the north aisle found in 2009 and is listed Grade I. St Martin was added to the original dedication to St Meriadoc in the 15th century. There is a western tower about 60 feet high containing eight bells (with a clock before 1882) and the aisles are identical in design: the building was gutted and restored in 1861-62 and an outer south aisle was added in 1878–79 to a design by James Piers St Aubyn. The church was re-opened on 7 August 1879 by Edward Benson, the Bishop of Truro.
