The Pedersöre (Pietarsaari) church is one of the oldest in Ostrobothnia. There have been wooden churches from the 13th century and the present stone church was built 1510-1520.
The church was modified to cross shape in 1787-1795 by famous church builder Jakob Rijf. Pedersöre Church was damaged badly by fire in 1986. It was supposed to be an arson, but any suspects were never found.
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.
