St Mary's Well in Aberdaron is a spot where the eerie sounds of screaming and chanting have been reported at dusk. These unsettling noises are believed to emanate from Bardsey Island, a place steeped in history and legend. The island, located just off the coast of Aberdaron, has a rich spiritual heritage, having been home to a monastery since the 6th century. It's easy to imagine the haunting cries carrying across the water, especially during the evening hours when the atmosphere is already charged with an air of mystery.

Historically, Bardsey Island has been a site of great spiritual significance. The island's monastery was an important centre of learning and worship, and it's said that over 20,000 saints and holy men are buried there. Given this context, it's perhaps not surprising that strange sounds have been reported in the area. The phenomenon of screaming and chanting being heard from St Mary's Well has been documented as far back as the 1950s and continues to be reported to this day, with instances recorded as recently as July 2019. The fact that these occurrences are typically noted during the evening adds to the sense of enigma, as if the veil between the worlds is at its thinnest during this time.
