The remarkable flat sandy Magilligan peninsula forms part of the northern boundary of the Limavady Borough and is of particular interest for historical and scientific study. Close by at Magilligan, the Western Education and Library Board maintains an outdoor education centre to facilitate field studies. At Magilligan Point, a well preserved Martello Tower built during the Napoleonic Wars with walls over 9ft thick marks the entrance to Lough Foyle were transatlantic liners once halted to make their first port of call in the old world. A ferry service is planned to operate between the Point and the County Donegal village of Greencastle, less than a mile across the Lough. Magilligan is named after the family who were the hereditary farmers of the church lands of a former monastery at nearby Duncrun, and is an interesting case of a parish preserving a clan name, the older form being Ard MacGilligan. Magilligan was the home of a famous Ulster Harpist, Denis O'Hampsey who is buried in St Aidan's Churchyard. In November 1998 Limavady Borough Council erected a memorial to this musical genius at the O'Hampsey family grave.
