The reformed church of Easterlittens was in catholic times known as St. Margaretha. The one-aisled nave was built in the 12th century, partly of tuff. The brick choir dates from the 13th century. In the 15th century the windows were enlarged and a sacristy was added to the north side. The south wall has a portal in manneristic style from 1655. The brick tower dates from 1854 and was designed by F. Stoett in a more or less neo-Romanesque style.

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.
