Askerton Castle is a rare example of a fortified medieval manor house, situated in remote north Cumbria, about three miles north of Hadrian's Wall. The original building was constructed around 1290 as an unfortified hall, but in the late 15th century, two battlemented towers—the Dacre Tower and the Dovecot Tower—were added by Thomas, Lord Dacre, as part of a border defense against the notorious Border Reivers. In the 16th century, the complex was expanded with a stable block and additional wings for troop accommodation. A third tower on the northwest corner is believed to have been lost, possibly to fire, but traces of its stonework and staircases are still visible in the walls. The structure contains impressive oak beams, dated between 1494 and 1510, and shows clear stages of architectural evolution—from a simple hall to a military stronghold. Although the castle is not open to the public, it is now part of the Askerton Castle Estate, an organic farm that produces beef, lamb, pork, and poultry. The building is a Grade I listed building, indicating its exceptional historical value.

Kielder Castle is a charming 18th-century hunting lodge in Northumberland, built in 1775 for the Duke of Northumberland.
