Roman Walls of Lugo

Lugo, like some other UNESCO sites in Galicia, looks a good place to visit when I return definitely to my country 

Roman Walls of Lugo

This postcard was sent by Vanesa

The Roman walls of Lugo were constructed in the 3rd century and are still largely intact today, stretching over 2 kilometers around the historic centre of Lugo in Galicia. 

The city walls were built between 263 and 276 A.D. to defend the Roman town of Lucus Augusti (present-day Lugo) against local tribesmen and Germanic invaders. The walls formed part of a complex of fortifications which also included a moat and an intervallum (the clearing between the walls and the city). The entire length of the walls is around 2,120 m, enclosing an area of 34.4 hectares. Not all of the town was enclosed by walls: much of the southeastern part of the town remained unprotected, while in other places unused areas were enclosed by walls. - in: wikipedia
