Hadrian’s Wall (Latin: Vallum Aelium, “Aelian Wall” – the Latin name is inferred from text on the Staffordshire Moorlands Patera) was a defensive fortification in Roman Britain.* Begun in AD 122*, during the rule of emperor Hadrian, it was the first of two fortifications built across Great Britain, the second being the Antonine Wall, lesser known of the two because its physical remains are less evident today.
The wall was the most heavily fortified border in the Empire. In addition to its role as a military fortification, it is thought that many of the gates through the wall would have served as customs posts to allow trade and levy taxation.
A significant portion of the wall still exists, particularly the mid-section, and for much of its length the wall can be followed on foot by Hadrian’s Wall Path or by cycle on National Cycle Route 72. It is the most popular tourist attraction in Northern England. It was made a UNESCO World Heritage Site in 1987. English Heritage, a government organisation in charge of managing the historic environment of England, describes it as “the most important monument built by the Romans in Britain”.
Hadrian’s Wall was 80 Roman miles (73 statute miles or 120 km) long, its width and height dependent on the construction materials which were available nearby. East of River Irthing the wall was made from squared stone and measured 3 metres (9.7 ft) wide and five to six metres (16–20 ft) high, while west of the river the wall was made from turf and measured 6 metres (20 ft) wide and 3.5 metres (11.5 ft) high. This does not include the wall’s ditches, berms and forts. The central section measured eight Roman feet wide (7.8 ft or 2.4 m) on a 10-foot (3.0 m) base. Some parts of this section of the wall survive to a height of 10 feet (3.0 m).
Hadrian’s Wall extended west from Segedunum at Wallsend on the River Tyne to the shore of the Solway Firth, ending a short but unknown distance west of the village of Bowness-on-Solway.3
Although the curtain wall ends near Bowness-on-Solway, this does not mark the end of the line of defensive structures. The system of Milecastles and Turrets is known to have continued along the Cumbria coast as far as Maryport. For classification purposes, the Milecastles west of Bowness-on-Solway are referred to as Milefortlets.
The A69 and B6318 roads follow the course of the wall as it starts in Newcastle upon Tyne to Carlisle, then along the northern coast of Cumbria (south shore of the Solway Firth). It is a common misconception that Hadrian’s wall marks the boundary between England and Scotland. This is not the case; Hadrian’s wall lies entirely within England, and south of the border with Scotland by less than one kilometre in the west at Bowness-on-Solway, and 110 kilometres (68 mi) in the east.
