St Tysilio's Church, Church Island
A small medieval church on Ynys Tysilio, a little island in the Menai Strait reached by a causeway at Menai Bridge. It’s ringed by its graveyard and looks straight out at the water, with the strait’s promenade walk running past. The exterior is open to wander round even when the church itself is locked. Bangor station is just across the water, about 2.5km away.
