Frontiers of the Roman Empire

A transnational UNESCO series that in the United Kingdom is represented by the Roman frontier known as Hadrian’s Wall, an engineered stone barrier across northern England dating to the early 2nd century AD. It marks the northern limit of Roman Britain and is about 117 kilometres long.

Walkable sections of the Wall offer extensive visible masonry, ditches and earthworks, plus a sequence of forts and milecastles spaced roughly every Roman mile. Key sites contain visitor facilities and museums that display finds such as inscriptions, armour and everyday objects.

Many forts are accessible on foot and provide views across the surrounding moorland and valleys; conservation and ongoing excavations at several forts continue to reveal new archaeological information. Interpretation along trails and at visitor centres explains the Wall’s military, administrative and logistical role in Roman Britain.

Construction began under Emperor Hadrian around AD 122 as a controlled frontier line and garrison system. The Wall was staffed by auxiliary units and linked to a chain of forts and supply routes; it remained a focus of Roman military presence in Britain until the legions withdrew in the early 5th century.

The Wall runs coast-to-coast across northern England from the River Tyne in the east to the Solway Firth in the west, crossing rural moorland and agricultural valleys and lying north of Newcastle and south of the Scottish border.

• Length and structure: The wall measures about 117 kilometres in length and includes a linked system of forts, milecastles and watchtowers spaced at regular intervals.
• Visiting tips: Best light and visibility for walking the central sections is typically late spring to early autumn; several museums along the route provide archaeological context and artifact displays.
