Cornia Nou is a settlement dating from the Talayotic period (1000-750 B.C.) with two well preserved talayots of different types. The oldest and most spectacular is circular and measures around 26 metres in diameter, an impressive monument. It has a building in the facade with access at ground level; an inside passageway ascends to a set of steps leading up to the upper platform of the talayot.The other talaiot is considerably smaller and has a distinctive feature of a passageway covered with stone slabs crossing its diameter and joined to a wall. Excavation work carried out in 2007 uncovered the remains of pottery items dating from the post-Talayotic period in the 3rd century B.C. Plus, near the site there is a large Islamic necropolis with burial chambers carved out of the rock, which supports the hypothesis that rural settlements from the Muslim period were built on top of the sites from the Talayotic period.
References:The city walls of Avila were built in the 11th century to protect the citizens from the Moors. They have been well maintained throughout the centuries and are now a major tourist attraction as well as a UNESCO World Heritage Site. Visitors can walk around about half of the length of the walls.
The layout of the city is an even quadrilateral with a perimeter of 2,516 m. Its walls, which consist in part of stones already used in earlier constructions, have an average thickness of 3 m. Access to the city is afforded by nine gates of different periods; twin 20 m high towers, linked by a semi-circular arch, flank the oldest ones, Puerta de San Vicente and Puerta del Alcázar.
