The Chapel of St Non is located on the coast near St David’s in Pembrokeshire, West Wales. Held by tradition to mark the birthplace of St David, the ruin cannot be accurately dated but is unusual in that it is aligned north-south rather than the usual east-west. Near to the ruined chapel is a retreat, a modern chapel and a holy well. The site was protected in the 1950s and is now the responsibility of the Welsh Heritage organisation Cadw.
