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 Walls of Constantinople are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. They were also the largest and strongest fortification in both the ancient and medieval world.
Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger.
