This site was occupied for longer than any other on Hadrian's wall. The township sprang up around the fort and supply base which lay north of the bridge carrying Dere Street. The wall runs along the rise to the north. The museum of the Corstopitum Roman Camp presents the layout of the site with its granaries, fountain, headquarters building and temples. From the elevated viewpoint there is a good overall view of the visible remains.

The remains of the Roman fort of Segedunum overlook the north bank of the River Tyne. The fort was the last outpost at the eastern end of the famous wall built by Roman Emperor Hadrian (AD 76-138). The wall was built to protect England from invasions from the north. The fort has a defensive wall and a ditch, and inside is a museum where visitors can find out about Roman garrison life. There is also a reconstructed Roman bathhouse and, from the tower, fine views of the surrounding area.

The fort (2 ha) is perched high on the ridge and is the most complete example of forts built along Hadrian's Wall. Still clearly visible are the foundations of the large courtyard house of the commandant, the granaries, barracks, headquarters building, the four main gateways, the hospital and the 24-seater latrine block, as well as part of the civilian settlement, clustering around the south gate.

Going up to Killhope, a little town situated in the valley surrounded by sheep fields, you can see admire the splendid countryside of the North Pennines. The stone of the buildings, trams and enormous paddle wheels illustrate the difficult working conditions of the 19C in this old mining area, as told by its two inhabitants, William and Phoebe Millaun.
