Stiklestad Church was built at the site of the Battle of Stiklestad and completed in 1180. During the battle in 1030, St. Olaf received three severe wounds—in the knee, in the neck, and the final mortal blow through the heart—and died leaning against a large stone. The church building is assumed to have been erected on the exact spot where St. Olaf was killed during that battle and that stone is supposedly still inside the altar of the church. The church was designed by Archbishop Øystein Erlendsson.

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.
