Immediately south of St Davids, this ruggedly beautiful spot is named after St David's mother and traditionally accepted as his birthplace. A path leads to the 13th-century ruins of St Non's Chapel. Only the base of the walls remains, along with a stone marked with a cross within a circle that's believed to date from the 7th century. Standing stones in the surrounding field suggest that the chapel may have been built within an ancient pagan stone circle.

　　On the approach to the ruins is a pretty little holy well. The sacred spring is said to have emerged at the moment of the saint's birth and the water is believed to have curative powers. Although pilgrimages were officially banned following the suppression of Catholicism in the 16th century, the faithful continued to make furtive visits.

　　The site has now come full circle. In 1935 a local Catholic, Cecil Morgan-Griffiths, built the Chapel of Our Lady & St Non out of the stones of former religious buildings that had been incorporated into local cottages and farms. Its dimensions echo those of the original chapel. The Catholic Church repaired the stone vaulting over the well in 1951, and Morgan-Griffiths' house is now used by the Passionist Fathers as a retreat centre.
