France: Langres

Langres is a fortified medieval town in the south of Champagne region of France and has a long history going back almost two thousand years. Given a geographic feature of a rocky promontory platform above the surrounding planes, this has been fortified first by Gauls, then heavily fortified by Romans (this was on a crossroads of 12 Roman trade routes), and then even heavier fortified by the French. The round town is surrounded by 3.5km of high walls (you need a funicular to even get up into town), with 12 towers and 7 gates. Once inside this fortress of a town – narrow cobblestone streets criss cross the area with several historic buildings and a 12th century cathedral.
