Trefor granite quarry

Trefor Virtual Tour

The Llŷn peninsula protrudes from the Snowdonia Massif and this lowland landscape is characterised by occasional dramatic volcanic granite peaks, which have been exploited over millennia as building material. Located on the northern coast of Pen Llŷn, just southwest of the village of Trefor (SH371467), lies one of these impressive granite peaks which formed the focus for extensive quarrying in modern times. The Trefor Granite workings on Garn Fôr, one of Yr Eifl’s hills in this spectacular coastal location, remain a dominant feature within an archaeologically rich landscape (the hillfort of Tre’r Ceiri sits on the eastern-most hilltop of Yr Eifl).

Immerse yourself in a virtual tour of this monument and its surrounds. You can also read an accessible description of the tour, and view an interactive map of the various granite workings around Trefor.
