York has been defended by walls since Roman times, and this walk strings together six places around them: the Multangular Tower, York Minster, Clifford's Tower, Micklegate Bar, the Shambles and Walmgate Bar.
Each stop is a moment in the city's story, from a Roman fort built around 71 AD to a siege in 1644.
Richard III's story runs from Middleham Castle in Yorkshire to Bosworth Field, where he died in 1485, and on to Leicester, where his grave was found under a car park in 2012.
The route follows his childhood at Middleham, the battle of Tewkesbury, the princes at the Tower of London, his last charge at Bosworth, and the Greyfriars dig and cathedral tomb in Leicester. The exact Bosworth battlefield is still debated.
