GeoMôn or Anglesey Geopark, 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.
Originally geoconservation on Anglesey was administered by the Gwynedd and Mon RIGS group, but a decision was taken to apply for Geopark membership. GeoMôn is a limited company, registered at Companies House, which administers the Geopark and currently has 4 directors, two geologists and two Isle of Anglesey County Council officials. The Geopark designation reflects the extraordinary diversity of the site'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.
