Heddal stave church is a triple nave stave church and is Norway's largest stave church. It was constructed at the beginning of the 13th century. After the reformation, the church was in a very poor condition, and a restoration took place during 1849 - 1851. However, because the restorers lacked the necessary knowledge and skills, yet another restoration was necessary in the 1950s. The interior is marked by the period after the Lutheran Reformation in 1536-1537 and is for a great part a result of the restoration that took place in the 1950s. What is known is that five peasants together with Sira Eilif built the church.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.
