a trailhead for the Cliff Walk which navigates a large section of Howth Head and ends at Howth village. Shielmartin Hill is also readily accessible from Sutton. Buildings One of the area's oldest buildings, the fifteenth century Corr Castle, is located at Sutton North near the Howth Road entrance to Offington housing estate. The castle previously formed part of the Howth Park Racecourse which stretched over large parts of Sutton and Howth. The area is also home to one of Ireland's Martello Towers at Red Rock which is now a private residence. Also located in Red Rock is Sutton Castle, the former home of the Jameson family, and later became the residence of Belgian businessman Albert Luykx, made famous during the Irish arms trial. It subsequently became Sutton House Hotel and then Sutton Castle Hotel, before being converted in 2003 to private residences. Several notable Georgian houses are located in Sutton including two imposing 4-storey Georgian era houses now called Beachfield House (previously called Devonshire Terrace) as well as the nearby Sealawn House (1830s) which was owned by John Pentland Mahaffy. Adjacent to these is a terrace of Howth stone-faced fisherman's cottages called Martello Terrace. The end house of this terrace used to house the old Sutton coast guard station but has now been converted into residential accommodation. The old tram shed which was used by the Hill of Howth Tramway is located near Sutton Station, but is now a private residence which is part of a modern housing development. The Luí na Gréine (English:Sunset) granite standing stone monument is located on the seaside pathway at Sutton strand and was designed by Cliodhna Cussen and erected in the mid-2000's.
