Penrhos Feilw Standing Stones

The Penrhos Feilw Standing Stones are a pair of standing stones on Holy Island west of Anglesey in north-west Wales [1]. They are thought to date from the Bronze Age but their origins and purpose are unclear [1]. The stones are located behind the farmhouse of Plas Meilw, some 2 km southwest of Holyhead and a similar distance south of Holyhead Mountain [1]. The exposed part of each stone is about 3 m high and 1 m broad at the base, but only about 20 cm thick [1]. They are situated about 3 m apart on an open grassy place above Porth Dafarch between two low hills [1]. They are aligned along their long axes in a northeasterly/southwesterly direction [1].
