The Avila walls are some of the best preserved defenses in Spain. Built between the 11th and 14th centuries, the 2,500 meter long walls surround the city.
Most sections are three meters wide and reach a height of about 12 meters. The defenses included almost 90 semi-circular towers built at intervals along the walls, as well as nine gates into the city, two of which feature twin 20 meter high towers. It's possible to walk along about half of the walls today, for views of the city and countryside.
Avila itself is well worth exploring too, for its old town and large number of Romanesque churches.Places nearby:
