St Sannan's Church, Bedwellty was built for a large parish, in a thirteenth century Gothic style. It is a long-wall entry type and consists of chancel, nave, north aisle, south porch, and a fourteenth century integral western tower containing six bells. The church was restored in 1858, and in 1882 was thoroughly repaired. An iron gravestone, dating from the 1770s is mounted on the south wall of the church. The church has a whitewashed exterior.
