The medieval stone church of Ås date back to the 12th century. It is the only church in Öland where the tower is located in the east side. The church was enlarged in 1770 and the interior is mainly from the 18th-19th centuries. The pulpit is very unusual; this nineteenth century work is directly above the altar, an arrangement rarely seen in Swedish churches. The church is long established as a landmark for seafarers. During the nineteenth century the tower was rebuilt to incorporate a lantern, so that it doubled as an early lighthouse.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.
