Medieval Walls of Ávila.

The Medieval Walls of Ávila are a stunning example of 12th-century military architecture, stretching 2.5 kilometers and standing up to 12 meters high. Initiated in 1090 by Alfonso VI following the conquest of Ávila, these walls are among the best-preserved medieval fortifications in Europe. They feature nearly 2,500 crenellations, 88 semicircular towers, and nine gates, including the prominent Puerta de San Vicente. Declared a UNESCO World Heritage Site in 1985, the walls are not only visually striking—especially when illuminated at night—but also provide visitors with panoramic views of the city and surrounding countryside. Accessible to the public, the site includes museums and audio guides, offering a rich insight into Ávila's historical significance and architectural heritage.
