An ancient Roman wall, 118.3 km (73.5 mi) long, across northern England. Built by order of the emperor Hadrian c. A.D. 122-126 and extended by Severus a century later, the wall marked the northern defensive boundary of Roman Britain. Fragmentary ruins of the wall and many of the "mile stations" (stone blockhouses along the wall constructed every Roman mile) remain. Though used as protection against the Picts and the Scots, these groups probably arrived after the wall was built. The British gov't has undertaken the preservation of the wall, which is one of the largest and most significant remains of the Roman occupation.

Scotland/England

A.D. 76-138 Emperor of Rome (117-138) who sought to end distinctions between Rome and the Roman provinces. During his visit to Britain (122), he ordered the construction of Hadrian's Wall.

Hadrian's Wall goes up in Britain following the arrival in the spring of the emperor Hadrian on a tour of military inspection. The 72-mile wall from the Tyne to the Solvay is built mostly of stone with at least 16 forts and will provide a defensive barrier against the Picts and other tribesmen to the north.

The Antonine Wall (a.k.a. 'The Roman Wall' or 'The Wall of Antoninus') goes up in Britain from the Firth of Forth to the Firth of Clyde (about 58 km /37 mi). It was named after the ruling Emperor Antoninus Pius. Built of turf on a stone foundation as a barrier against the Picts and Caledonians, the wall is 10 feet high, 14 to 16 feet wide, and will have 13 to 19 forts along its 37-mile length.

The Romans retreat from the Antonine Wall to the southern line at Hadrian's Wall.

The Romans begin pulling troops out of Britain and abandon work on Hadrian's Wall.

Picts and Scots cross Hadrian's Wall and attack Roman forces in Britain.
