The Preseli Hills, or Mynydd Preseli, are a range of hills in Pembrokeshire, Wales, that are part of the larger Cambrian Mountains. This area is renowned for its natural beauty, historical significance, and geological features.
The Preseli Hills stretch approximately 25 miles from Newport in the west to Fishguard in the east. The highest peak in the range is Foel Cwmcerwyn, which rises to 536 meters (1,759 feet). The hills are characterized by their rugged terrain, heather-covered moorlands, and prehistoric remains.
The geology of the Preseli Hills includes igneous rocks like dolerite, which forms the famous bluestones, and rhyolite. These rocks were formed during the Ordovician Period, approximately 460 million years ago. The unique geological formations have led to the area being designated as a Regionally Important Geological Site (RIGS).
The Preseli Hills have inspired artists, writers, and musicians. They are often depicted in Welsh literature and art, symbolizing the wild, untamed spirit of the Welsh landscape. The hills have also been the subject of folklore, with legends like the Afon Nyfer river being associated with the legendary King Arthur.
