Herritslev church was built around 1220 under the rule of Valdemar II of Denmark. The tower and vaults were added 150-200 years later in Gothic style. The pulpit, made in Dutch Renaissance style, dates from 1610. There are some frescoes in the vaults from the 13th century. In the cemetery on churchyard is a notable medieval stone wall.
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.
