The oldest parts of Rinkaby church were completed probably in the late 1100s. It was enlarged to the west and the sacristy was added sometimes in the 1200s or early 1300s. The vaulting was added in the late 1400s and the chapel in 1620. The major restoration was made 1779-1780 and in 1839 the current tower replaced the medieval one.

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.
