Castle Ward has been the home of the Ward family since ca. 1570. Known originally as Carrick na Sheannagh and owned by the Earls of Kildare, it was bought by Bernard Ward, father of Sir Robert Ward, Surveyor-General of Ireland. The 850 acre walled demesne also dates from the 16th century. The Ward family built a succession of homes in their estate; Old Castle Ward, built about 1590 near to Strangford Lough, still survives, but a mansion built about 1720 by Judge Michael Ward was demolished about 1850, although some of the associated landscaping remains.
The architect of the current building, built during the early 1760s for Michael Ward's son Bernard Ward, 1st Viscount Bangor is unknown, although he may have come from the Bristol area, with which the Ward family had associations. It may have been James Bridges who practiced in Bristol between 1757 and 1763 and whose work there has some similarity to Castle Ward.
The property was inherited by a settlement made in 1748 by Bernard Ward's eldest son, Nicholas, 2nd Viscount Bangor, who was clearly insane. When his younger brother, Edward, died in 1812, leaving a young son, the youngest brother Robert took the opportunity to relocate the insane Nicholas into a smaller house in Downpatrick and strip Castle Ward of everything valuable. The house stood empty until the death of Nicholas in 1827, when it was inherited by Edward's son, now the 3rd Viscount. He and his descendants restored the building and its furnishings, but on the death of the 6th Viscount in 1950 the house and estate were given in lieu of death duties to the Government of Northern Ireland, who presented the house and its gardens to the National Trust in 1952.
Castle Ward is open to the public and includes 332 hectares (820 acres) of landscaped gardens, a fortified tower house, Victorian laundry, theatre, restaurant, shop, saw mill and a working corn mill. It has a shore on Strangford Lough. There is a tower house in the estate's farmyard, built as a defensive structure during 1610 by Nicholas Ward.
References:Kakesbeck is one of the largest medieval fortifications in Münsterland and the oldest castle in Lüdinghausen. The imposingly grown complex originated in 1120 as a motte, a small hilltop tower castle. After numerous changes of ownership, the castle was extended onto two islands, but it was not until the 14th century that it underwent significant alterations and extensions under the von Oer family. The estate experienced its heyday in the middle of the 18th century, when it covered an area of almost one square kilometre and consisted of five further outer castles in addition to the core castle, which were secured by ramparts and moats.
The well-maintained condition of the castle today is thanks to the late Wilfried Grewing, the former lord of the castle. The foundation named after him has been particularly committed to preserving the property since 2020.
