This is a popular resort with a fine beach. It is an important commercial fishing port. It was once a place of historical importance. Richard de Burgo (often latinised as Richard de Burgo), the Red Earl of Ulster, selected the place as a site for a castle to dominate the O’Donnells and the O’Dohertys of Inishowen.This village has been synonymous with the sea for centuries and many generations of its people have sailed the seven seas. It is therefore only fitting that there is a Maritime Museum and Planetarium that houses hundreds of relics of the sea. The Irish National Fisheries College is also located here preparing young men and women for a life at sea. During the summer months, the ferry crosses the Foyle to the Causeway Coast – it links Greencastle with Magilligan Point; both popular seaside locations.
