Its huge town walls and well-preserved medieval city centre make Àvila one of Spain's most popular destinations, and a trip there adds an element of time travel. Wandering its streets and visting its many Gothic and Romanesque churches puts one right into the 16th century, with local saints Theresa and Juan de la Cruz about to appear at any moment. I only had a couple of hours to spend in this impressive city, but I managed to fit in a visit to the cathedral (which is actually integrated into the city walls), the basilica of San Vicente, the Convent of Santa Teresa, and the Royal Monastery of Santo Tomás, with its interesting museum and 3 cloisters.
