See the exterior of the Ávila Walls that surround the city that was completed in just 10 years, between the 11th and 14th centuries. Then, visit the outside of the Basilica of San Vicente known as The Basilica of the Holy Brothers Martyrs, Vicente, Sabina, and Cristeta.

Finish at El Alcázar de Segovia, a medieval fortress, located on a rocky crag on the confluence of two rivers near the Sierra de Guadarrama, it is one of the most distinctive castles-palaces in Spain by virtue of its shape, like the prow of a ship.
