The name Betws is thought to be derived from "bead house," meaning a place of prayer (y coed – in the woods). It's likely that 14th-century St Michael's Church, the town's oldest building, stands on the site of that early sanctuary. The main item of interest inside is a stone effigy of Gruffydd ap Dafydd Goch, possibly the grandnephew of Llywelyn ap Gruffydd, the last native Prince of Wales. If closed, the Railway Museum should have the key.
