Söderby-Karl Church was built around 1300 or soon later. The porch was added later in the 1300s and brick arches in the mid-1400s. The external bell tower was erected probably in 1664. The main restoration was done in 1790. The interior is decorated with beautiful murals from the late Middle Ages which have never been overpainted. The sandstone font dates from 1200s.

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.
