Book Description: Hadrian’s Wall Path, 84 miles from end to end, follows the course of northern Europe’s largest surviving Roman monument, a 2nd-century fortification built – in the border country between England and Scotland – on the orders of the Emperor Hadrian in AD122. Hadrian’s Wall Path is the first National Trail to follow the course of a UNESCO World Heritage Site. It is proving an immensely popular walk and in the first 18 months of its opening in 2003 it attracted almost 400,000 walkers.Â
