The gatehouse reconstruction of Hylton Castle

Hylton Castle in Sunderland was originally built of wood by the Hylton family shortly after the Norman Conquest. In the late 14th to early 15th century, Sir William Hylton rebuilt it in stone as a four-storey, gatehouse-style, fortified manor house. While it was called a gatehouse, it is a type of small, late-14th-century castle similar in design to Old Wardour and Bywell.

During the 18th century, the castle underwent significant internal and external changes. In the early 1700s, John Hylton gutted the interior to form a three-storeyed block and added large, alternating, pedimented sash windows in the Italianate style. He also added a three-storeyed north wing. After 1728, John Hylton, de jure 18th Baron Hylton, added a complementary south wing, added crenellations to both wings, and changed a circular bartizan on the north end of the west front into an octagonal turret.

The west façade features a range of heraldic devices that have been retained since the original stone reconstruction. These devices depict the coats of arms belonging to local gentry and peers from the late 14th to early 15th centuries. These carvings provide an approximate date for the castle's transition from a wooden structure to a stone building.

Today, the castle and its chapel are protected as a Grade I listed building and a scheduled monument. English Heritage manages the site while a community organisation maintains the surrounding parkland. Plans have been announced to turn the castle into a community facility and visitor attraction, with funding provided to create classrooms, a cafe, and rooms for exhibitions and meetings.
