Flesberg stave church was probably built around 1200. The first written reference to the church is from 1359. The church was originally a single nave church with four free-standing internal posts bearing a raised central roof, surrounded by an ambulatory or aisles on all four sides. It had a narrower chancel, also with a raised central roof, and a semicircular apse. It was surrounded by a gallery loosely connected to the plank walls.
In 1735, the chancel and apse as well as the east wall of the nave were removed. The nave was extended eastwards and two transepts were added, making a cruciform plan. The additions were built in horizontal log construction with notched corners. Of the original stave church only three outer walls survived, as the internal posts and the raised roof were eliminated.
The church yard is fenced with big slates brought from Haukeli farm (on the Lågen west bank) during winter seasons. Some slates have iron rings affixed, these rings were used for tying horses during service - each farmer had a designated ring for his horse (the oldest dated ring from 1661). The idiosyncratic stone fence is shown on a 1701 painting (the oldest existing painting of a stave 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.
