Husaby Church is one of the most interesting historical sites in Sweden. The first stave church was built probably in the 10th century. Olof Skötkonung, the first Christian king of Sweden, is rumoured to have allowed himself to be baptised at a well by the church in 1008. Husaby was also the seat of bishop until 1150s.
The present church was built in the early 1100s and influenced by German and English missionaries. Architecturally, it is remarkable for its steep walls and high towers, arguably the only Romanesque architecture in Sweden of that kind. Arches were added in the 15th century.
The most interesting artefact inside is the medieval bishop’s seat. There are also two graves, which (according to tradition) belong to King Olof Skötkonung and his wife Estrid.
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.
