This tiny, plain stone roofed building is about 11 feet by 8 feet, with walls two feet thick and, under the altar, St Trillo's holy well.
Is this the smallest church in Britain? With seats for just six people, it may well be a contender for the title. Dating to the early 16th century, the chapel may have been built on the site of an older church on the orders of the Cistercian monks at Aberconwy Abbey. In 1935 the chapel was carefully restored and reconsecrated by William Thomas Havard, Bishop of St Asaph.

"This fascinating building is thought to be the smallest church in the British Isles, seating only 6 people. It is named after St. Trillo, a 6th century Celtic saint who built his cell here. The age of the present building is not known, as it has been heavily repaired over the centuries. St. Trillo’s original cell is more likely to have been made of wood and wattle, although he may have built a wall of stones gathered from the beach to protect it from the wind."
