"Saint Trillo is the patron saint and founder of the churches at Llandrillo, Denbighshire and Llandrillo yn Rhos, Rhos-on-Sea in Conwy County Borough, Wales. According to Enwogion Cymru, Trillo was a saint who lived in the early part of the sixth century. He was one of the sons of Ithel Hael. Trillo was nobly born in Brittany and went to Wales as a disciple and student of Saint Cadfan, who later admitted Trillo to the religious life. Trillo became an Abbot and church-founder, noted for his holiness." St Trillo's chapel is the smallest chapel in Britain and stands on the foreshore (now protected by extended promenade and sea wall) at Llandrillo yn Rhos (Rhos-on-Sea). Its a simple stone and mortar structure with integral walls and roof and has a heavy wooden door. It was heavily restored in its present form with new external walls and roof about 120 years ago. Its altar stands over a natural spring of clear water dedicated to St Trillo and St Elidan and was first established by Saint Trillo early in the sixth century AD. The chapel has seats for six people and is used for an Anglican Eucharist every Wednesday. The spring water is traditionally used for baptisms in that parish which has two other Anglican Churches.
