In September 2020 NWARG held a special event station GB1STC to celebrate “chapels on the air” from the smallest chapel in Britain, The Holy Well and Chapel of St Trillo, Colwyn Bay, North Wales
The chapel stands on the foreshore at Llandrillo yn Rhos, Rhos-on-Sea, Colwyn Bay. Its a simple stone and mortar structure with integral walls and roof and has a heavy wooden door.
The 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.
