Husaby Church is one of the most interesting historical sites in Sweden. The first stave church was built probably in the 10th century. Olof Skötkonung, the first Christian king of Sweden, is rumoured to have allowed himself to be baptised at a well by the church in 1008. Husaby was also the seat of bishop until 1150s.
The present church was built in the early 1100s and influenced by German and English missionaries. Architecturally, it is remarkable for its steep walls and high towers, arguably the only Romanesque architecture in Sweden of that kind. Arches were added in the 15th century.
The most interesting artefact inside is the medieval bishop’s seat. There are also two graves, which (according to tradition) belong to King Olof Skötkonung and his wife Estrid.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.
