These two towns in the region of Castilla y Leon are famous for their impressive historical constructions. The town of Avila is located on higher ground where the weather is cooler, and is famous for its fortifications. Founded in the 11th century, city protected itself with an impressive wall with 82 towers that continues to enclose the town. Avila continues to preserve its medieval look today and is well-known for its continued nearly-complete preservation, winning it an inscription in the UNESCO world heritage. Segovia, located in a relatively barren area, contains three UNESCO world heritage sites including the extraordinary two-tiered, cement-less Roman aqueduct built ca. 50 AD.
