Coming down hill towards Ardglass from the Erasmus School and the Catholic St Nicholas’s Church on High Street, you come to Kildare Street and find King’s Castle is on the left.

King's Castle was built on the site of the two 14th century tower-houses that stood at the entrance to Ardglass in days of yore.

Corn merchants were doing well in Lecale  coastal villages in the first years of the 19th century, and Charles Russell, a corn merchant from Killough was able to deliver this imposing institution. It later became a religious retreat for Catholics and is now a nursing home.

Charles Russell was a distant relative of George Russell the Norman-Irish local leader of the 1641 rebellion in Lecale.
