Part of Hadrian's Wall © Alun Salt
In order to separate the Roman Empire in Britain from the native 'barbarians,' Emperor Hadrian ordered the building of an impressive wall in the year 122. Taking approximately six years to complete, the wall stretches for roughly 80 miles (120km) from South Shields to Ravenglass, passing through present-day Newcastle. Dotted along it are several forts, temples, turrets and mile castles, and visitors can explore these fascinating 2,000-year-old remains, as well as the often stunningly beautiful surrounding countryside. Hadrian's Wall was declared a UNESCO World Heritage Site in 1987, and continues to delight and amaze historically-minded visitors to the north of England.
