in Gwynedd World Heritage Site. Oriel Ynys Môn is the municipal art gallery and museum dedicated to local artists and crafts. Anglesey’s two most important artists have exhibitions there. Firstly, there is an exhibition of the work of Charles Tunnicliffe, the wildlife artist and then Sir Kyffin Williams RA, whose work is shown in a new gallery dedicated to him. He was a founder member of the Geopark and its first patron. His great uncle, Sir Andrew Ramsay, was the second Director General of the British Geological Survey of Great Britain and a ‘Father’ of Welsh Geology; he died in Beaumaris and is buried in the churchyard at Llansadwrn, under a glacial erratic, a boulder of Shap Granite. 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 administered by GeoMôn-Anglesey Geopark Limited, a company registered at Companies House, and a registered charity. GeoMôn produces books on the geology of the island as well as leaflets detailing a number of self-guided trails. There is a Geopark visitor centre open from 10am to 4pm every day except Monday, at the Watch House in Porth Amlwch. Porth Amlwch was created mainly to facilitate the export of copper ore from the mines on Parys Mountain. The Watch House was originally the waiting place for the pilots guiding sailing ships in and out of the tiny harbour. IUGS geological heritage site In respect of the site having 'spectacular, accessible and well-preserved exposures of late Neoproterozoic-Cambrian mélange with more than 200 years of study', the International Union of Geological Sciences (IUGS) included the 'Ynys Llanddwyn late Neoproterozoic-Cambrian Mélange' in the tectonics chapter of The First 100 IUGS Geological Heritage Sites published in October 2022. The organisation defines an IUGS Geological Heritage Site as 'a key place with geological elements and/or processes of international scientific relevance, used as a reference, and/or with a substantial contribution to the development of geological sciences through history.'
