Drotten Church was built around 1050 and it was the second largest church in Lund. The building was about 50m long and probably made for bishop’s church. Archaeologists have also found evidences of even earlier stave church on the site, built probably in the 990 by Danish King Svend Tveskæg.
Drotten Church was rebuilt several times and since 1150 it functioned as a parish church and later an abbey church. The church was demolished during the Reformation in 1500s. The excavations in 1980s revealed the well-preserved remains of the church and abbey. Today there is a museum.
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.
