How the name happened
The strong fjord
Norse longships came in through the Narrows in the 9th century and named the channel strangr-fjǫrðr — strong fjord — for the tide that runs through it at six knots. The Irish kept the Norse name, anglicised it as Strangford, and used the original Irish — Loch Cuan, the calm lough — only for the inland water itself. The village picked up the harbour name; the lough kept the older one.
Castle Ward becomes the Starks
Winterfell
HBO arrived at Castle Ward in 2010 to shoot the pilot of Game of Thrones. The 18th-century farmyard played the Winterfell courtyard, the archery range where Bran practised, and Robb Stark's army camp. Audley's Castle a mile north stood in for the Twins in the Red Wedding episode. The Trust now runs guided tours, costume hire and archery sessions. The cycling trail links twenty filming locations on the estate.
AD 432, allegedly
Saint Patrick's landing
Tradition has it that Patrick's ship was driven into Strangford Lough by adverse winds in 432 and he came ashore near Saul, two miles inland. He founded his first Irish church there in a barn given to him by the local chief Dichu. He died at Saul and is said to be buried up the road at Downpatrick. The Lecale peninsula is the most Patrician scrap of ground in Ireland; Strangford is its front door.
Castle Ward, the disagreement
Two houses, one wall
Bernard Ward, first Viscount Bangor, built Castle Ward in the 1760s. He wanted Palladian; his wife Lady Anne wanted Strawberry Hill Gothic. They could not agree, so the house was built half each — classical on the entrance front, gothic on the lough side, the dividing line running straight through the middle. The marriage did not survive the construction. Lady Anne left for Bath. The house stayed.
