Roman Walls of Lugo

The Roman walls surrounding the Old Town of Lugo in Galicia, Spain, built between 263 and 276 AD to defend the town of Lucus Augusti. The fortifications stretch 2,117 m with heights of 8-12 m and widths up to 7 m, retaining 85 external towers and 10 gates, five of which are original Roman. Built of slate and granite facings with a conglomerate core bound by lime mortar, they are the finest surviving example of late Roman military fortifications in western Europe. Inscribed as a UNESCO World Heritage Site in 2000, the entire circuit remains intact and walkable. The city celebrates its Roman heritage annually with the Arde Lucus festival.
