Milecastle 42 is one of those spots on Hadrian’s Wall that feels like you’ve just stumbled on a hidden gem. It’s not huge, but that’s part of the charm – you can properly picture the Roman soldiers posted here, staring out across the wild Northumberland landscape and wondering what on earth they’d signed up for. The views are cracking, the ruins are well-marked, and it gives you that instant connection to history without being swamped by crowds. A quick stop, but a memorable one – exactly what you want on a wall walk.

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.
