Eidsberg church, also called as Østfold Cathedral, was built in the late 1200s, but burned in 1440. The church was rebuilt, and in 1880-81 it was extended and restored to its present appearance. The wall is derived in part from the old medieval church. Findings suggest an early church about the year 1000, followed by a Romanesque church in 1100-tallet. Alteret the current church is from 1651, the pulpit from 1662. The baptismal font made of soapstone is from the Middle Ages, and two sculptures - Adam and Eve from the 1600s.
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.
