The Raisio Church was built between years 1500 and 1520. The church is dedicated St. Martin, a medieval Catholic saint. His picture is also placed in the Raisio city coat of arms. The oldest artefact in church is the triumph crucifix from the 14th century. The wall paintings are mostly from the 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.
