Housesteads Roman Fort is an auxiliary fort on Hadrian's Wall in Northumberland. It sits at the end of a one-mile crag of the Whin Sill, which the Wall runs over, overlooking sparsely populated hills.

Carlisle Castle guarded the western end of the Anglo-Scottish border for hundreds of years and survived seven sieges by the Scots between 1174 and 1461. It was later adapted for artillery, and in 1568 it held Mary Queen of Scots prisoner. It stayed in military use well into the 20th century.

Aydon Castle is a fortified medieval manor house near Corbridge in Northumberland, and is thought to be one of the least-altered examples in England. Begun in the late 13th century, it was progressively turned into a miniature castle as Anglo-Scottish border warfare grew fiercer, and was attacked at least three times by Scots raiders.

Tip: English Heritage lists it as closed for winter, so check it has reopened before you travel.

Prudhoe Castle is a ruined medieval castle on the south bank of the River Tyne in Northumberland, now looked after by English Heritage. It sits on a ridge above the river and guarded an important crossing. You approach past a mill pond, through the 14th-century barbican and over the inner ditch to the formidable gatehouse.

Tip: Check the English Heritage website before you go, as access to the inner ward and chapel is limited to certain days. There is free parking a short walk from the entrance, along a slope with cobbles and loose gravel.

Washington Old Hall is a stone manor house in the heart of Washington village, cared for by the National Trust. It includes parts of the medieval home of George Washington's direct ancestors, and the family took its surname from here. The ground floor shows a 17th-century home, with carved oak furniture and a collection of Delft ware.

Tip: Free parking is available on The Avenue, right beside the property.

Hermitage Castle is a semi-ruined stronghold in the remote valley of the Hermitage Water, in Scotland's wild border country. It was targeted for 400 years because of its role in controlling the Scottish Middle March, and it has a name as one of the most sinister and atmospheric castles in Scotland.

Tip: In the summer season (1 April to 31 October) it is covered by the Historic Environment Scotland Explorer Pass, but not in winter, so check before you go.
