The cemetery was built for the near Pitkäniemi mental hospital. Total of 426 patients were buried to the cemetery between 1902-1964 before it was abandoded. Because the human dignity of mental patients was not very high 100 years ago, only small tombstones or no tombstone att all were added to graves. The chapel was burned down more than half century ago.
There are also some remains of old trenches near the cemetery. Those were built by the Russian army during the First World War to defence Finland against the potential occupation of Germany.
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.
