Rømø church was built around 1200 but extended in the 17th and 18th centuries when the island prospered due to whaling. The church is consecrated to the patron saint of sailors, St. Clemens and many ship models, donated by seamen, are hanging in the church. During the last century, rights to have one's name on a church pew were sold, the proceeds being used for church expenses, and many of these can be seen on the pews in the church today. Very interesting churchyard with old headstones of the ship commanders and their families, British and German pilots from World War II.
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.
