Övraby Church was built in the 1100s. The porch and tower were added in the 15th century. The church contains some interesting frescoes, whitewashed over after the Reformation and only rediscovered at the beginning of the 20th century. Experts have dated these to the 12th century, making them some of the oldest surviving church frescoes in Scandinavia. The pulpit and altarpiece are both from the early 17th century.
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.
