One of the most beautiful and characteristic images of Astorga are the walls flanking the historic center, with the buildings of the Cathedral and the Episcopal Palace just above. It's an image worth seeing. Although there are remains of Roman walls in Astorga, which were built on top between the 13th and 15th centuries. Two sections have been perfectly preserved, one across the street from The Melgar, and the other between the Garden of the Synagogue and the walk to the Wall. They are impressively tall and are characterized by several circular cubes every 15 meters. From the Paseo de la Muralla, you can access the historic centre via a metal staircase, directly to the Episcopal Palace.
