The author Coxe states in 'Haunted Britain' that there have been three churches in Perranzabuloe. If you visit the current one (pictured above), you can discover more about the “lost church” which lies in the sand dunes nearby. This ancient church, known as St. Piran's, was hidden beneath the sand for centuries before its discovery and is believed to be one of the oldest places of worship in the British Isles.
Legend has it that St. Piran landed on Perran beach from his native Ireland and built the oratory in the Irish style. The first oratory was probably built of wattle and daub and replaced in stone at a later date. The oratory was very simple in plan and was approximately 30 feet long.
