St Tecla's Chapel or St Twrog's in the Severn Estuary was featured in the very interesting Archaeology programme: Britain At Low Tide on Channel 5 Saturday 17th March at 8.00pm. They found that the chapel was of a 14th century date and had been a hermitage, or anchorite's cell. But had fallen into ruin by the 17th century maybe due to higher tides in the estuary. The beacon is now solar powered. They called the chapel St Twrog's, but eventually they re-named it St Tegla's island, and also Church Island.
