St Gwenfaen's Well (also known as Welsh: Ffynnon Gwenfaen, Welsh: Ffynnon Wenfaen and Welsh: Ffynnon Gwenfai) is an early medieval holy well in the south west of Holy Island, Anglesey, named after St Gwenfaen, whose cloister was nearby. The site includes substantial remains of a building and is both a scheduled monument and a Grade II listed building. Traditionally, a gift of two white quartz pebbles thrown into the pool can cure mental health problems.
