The wall that defended the northern frontier of Britain was the most important monument built by the Romans in England. Emperor Hadrian ordered the construction of the wall in 122AD after he had visited Britain.
The wall runs for 73 miles (117 km) from Wallsend on the River Tyne, in the east, to Bowness on the Solway Firth, in the west. Along the wall were towns, forts and milecastles, many of which can be visited today.
Corbridge was a Roman garrison town, Chesters was a cavalry fort with bath house, Housesteads is the best preserved fort on the wall and Vindolanda is where ancient writing tablets have been found, packed with information about life in Roman times.
