The Franciscan Monastery in Enköping was built during the 1200s, probably around 1250. The founder is alleged to have been a Peter Olai from Roskilde. In a letter to the monastery from 1275 Master Palne asks to be buried there, when his wife is already buried in the monastery. For this, he promises a large sum of money, a boat and a tent as gifts to the monastery. The monastery was reconstructed several times during the Middle Ages. The single nave church was built first and enlarged later.
in 1530 Gustav Vasa of Sweden wrote a letter to the monastery, where he ordered it to operate as a hospital for poor lepers. The letter also states that the monks are not obliged to stay, but if they want to help patients they are allowed to stay. Hospital was moved later in the 1530s back to Stockholm, and the monastery's operations may have ceased completely around 1540, probably due to the Reformation.
Monastery buildings were demolished finally in the 1600s, but parts of the monastery was used still in the manufacturing of gunpowder. In the 1930s excavations revealed the remains of the monastery. Towards the end of the 1980s an extensive renovation of the park area was undertaken. The place of the monastery is marked by a large brown cross and stones.
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.
