Said to have been built in the eighth century, St Pirans is submerged beneath the sand in Perran Bay, with an inscribed stone marking the site. It is made up of a rectangular building containing a nave and chancel, with a bench stone surrounding the interior. A fifth-sixth century stone with Roman capitals is incorporated into one wall. The later church of St Piran on Perran Sands was built in about 1150, enlarged in the fifteenth century and abandoned in 1804. Some of the stone and interior fittings were moved to a new site further inland at Perranzabuloe. The foundations remain and near to the church is St Piran's Cross. The site can be reached via a footpath across the dunes from the coastal path and inland from Gear Farm.
