England: Durham
The historic city of Durham (a UNESCO World Heritage Site) sits almost completely on a peninsula created by the bend of the river Wear. It’s of relatively small size and then most of it is occupied by two complexes – the Durham Cathedral and the Durham Castle, both from the 11th century. The entire town is a hill so all the cobblestone streets (and there are only a couple) lead up to the cathedral, towering in the middle, packed with medieval treasures inside and out.
