Emperor Hadrian's monumental defensive wall marking the northern limit of the Roman Empire, stretching 73 miles across northern England. Best preserved Roman frontier in the world, with milecastles, turrets, and forts.
Hadrian's Wall was constructed on the orders of the Emperor Hadrian beginning in 122 CE, following his inspection of Britain's northern frontier that year, and was completed in roughly six years by legions of the Roman army. Stretching 73 Roman miles (approximately 117 kilometres) from Wallsend on the River Tyne in the east to Bowness-on-Solway on the Solway Firth in the west, it represents the most substantial Roman frontier fortification in the world and the northernmost limit of the Roman Empire at its greatest extent. The wall was originally built in stone through its eastern two-thirds and in turf in the west, with the turf sections later rebuilt in stone.
The wall averaged 3 metres in width and stood between 4.5 and 6 metres high, topped by a parapet walk. Every Roman mile along its length a milecastle — a small fortlet gatehouse — was built, and between each pair of milecastles stood two signal turrets. Seventeen major auxiliary forts were positioned along the wall to house garrison troops, including Housesteads (Vercovicium) and Chesters (Cilurnum). South of the wall, a flat-bottomed earthwork ditch known as the Vallum ran parallel to it, marking a military exclusion zone. North of the wall, a deeper V-shaped ditch served as the primary physical obstacle to attack.
The wall was abandoned and reoccupied several times over its operational life of nearly three centuries, finally ceasing military use as Roman authority withdrew from Britain in the early 5th century CE. Much of its stone was subsequently reused in local buildings, but substantial sections survive, particularly along the dramatic Whin Sill escarpment in Northumberland between Greenhead and Chollerford. Housesteads Fort on this central section is the most complete Roman auxiliary fort in Britain, with visible barracks, granaries, headquarters building, and the remains of a Roman latrine block with a communal drainage channel.
The nearby site of Vindolanda, which predates the wall itself and served as a garrison fort throughout its active period, has produced the Vindolanda writing tablets — the oldest surviving handwritten documents in Britain, dating from around 90 to 130 CE and recording mundane military life including a birthday party invitation and complaints about British weather. The wall and its associated forts were inscribed as a UNESCO World Heritage Site in 1987, extended under the broader Frontiers of the Roman Empire designation. The Hadrian's Wall Path National Trail follows the full 84-mile length from coast to coast.
Why it matters
Hadrian's Wall is the best-preserved Roman frontier fortification in the world, built in 122 CE to mark and defend the northernmost limit of the Roman Empire in Britain, and remains the most tangible physical legacy of three centuries of Roman military occupation across the United Kingdom.

Tips for visiting
- Most open-countryside sections are free; English Heritage charges for Housesteads Fort (adult approximately £9.50)
- The Hadrian's Wall Country Bus (AD122) runs seasonally between Hexham and Haltwhistle, connecting key sites without a car
- Combine Housesteads Fort with Vindolanda in a single day — they are a short drive apart and tell complementary stories
- Walk the Steel Rigg to Crag Lough section (about 3 miles) for the most dramatic stretch of surviving upland wall
- Wear walking boots and waterproof layers; the central moorland sections are exposed in all seasons
- Visit in late spring or early autumn for drier ground, lower visitor numbers, and good photographic light
- The Vindolanda museum is not managed by English Heritage; a separate admission applies and includes access to active excavations in season
Frequently asked questions
How long does it take to visit Hadrian's Wall properly?
A single-day visit focused on the central section with Housesteads Fort takes 4 to 5 hours. Walking the full Hadrian's Wall Path coast to coast takes 7 to 9 days for most hikers.
Is Hadrian's Wall accessible for visitors with mobility limitations?
The visitor centres and fort museums at Housesteads, Chesters, and Vindolanda have accessible paved paths within the remains. Open-countryside wall sections cross steep moorland terrain that is unsuitable for wheelchairs.
Do visitors need a car to reach the main sites?
A car is the most flexible option, but the seasonal AD122 bus runs from Hexham and connects the main sites along the central section. Hexham and Haltwhistle have rail connections to Newcastle.
What is the best single section of the wall to visit?
The stretch between Steel Rigg and Housesteads Fort on the Whin Sill escarpment combines the most dramatic surviving wall with a complete fort and panoramic moorland views, making it the recommended choice for a first visit.
