GeoMôn UNESCO Global Geopark is a Geopark covering the entire island of Anglesey in North Wales. It was admitted to the European Geoparks Network and to the UNESCO-assisted Global Network of National Geoparks in May 2009. It is the second Geopark to be designated in Wales, the seventh within the United Kingdom and the thirty-third in Europe. The UNESCO Geopark designation reflects the diversity of the island's geology, which encompasses solid rocks from the Precambrian to the Neogene with some Miocene sediments and extensive Pleistocene glaciation features from the Quaternary period. GeoMôn covers 720 square kilometres and has 125 miles of coastal walks. The Isle of Anglesey lies off the north coast of Wales, UK. It is known as Ynys Môn in Welsh. Around 67,000 people live on the island. The local culture is very distinctive, with around 60% of the population using Welsh as their first language. The island is renowned for its diverse tectonic geology. South Stack with its world class folding and faulting has been a controversial site for many years, having been first identified as the oldest Precambrian rock then the youngest and now said to be from the Cambrian period. It is a mecca for students and schools who come here to study folding and faulting as well as examining the evidence for the birth of the Atlantic. Llanddwyn Island on the west Anglesey coast is a small, but complete oceanic plate, with the pillow lavas at its eastern end created at a Precambrian constructive plate margin. The plate interior on the northern coast is composed of mudstones and sandstones, some containing ‘dropstones’, the remnants of the Gaskiers Ice Age that occurred at the end of Precambrian times. Anglesey is the type locality for a rock type christened "mélange" by Edward Greenly when he first mapped the geology of Anglesey in the early years of the twentieth century. GeoMon publishes a series of local trails to guide the visitor around the coastal areas of the island served by the 125 mile long coastal path. The trail at Beaumaris illustrates the use of rocks in the building of the 13th century castle, roofs and roads as well as more ornate carvings on wealthier buildings. The castle built by King Edward I was intended to ‘tame’ the local Welsh people and keep them in order. It is part of the Castles and Town Walls of King Edward
