The Roman walls of Lugo are the ancient Roman defensive walls of the Roman colonia of Lucus Augusti –present-day Lugo, Spain–, in the Roman province of Hispania Tarraconensis. Stretching 2,120 metres (6,960 ft), they were built in the third century AD to defend the ancient Roman town. The fortifications, still largely intact, were declared a UNESCO World Heritage Site in 2000 and are a popular tourist attraction.
