The first church built in Hossmo was most likely a wooden one. Coffins found show that there was probably a church here already in the 11th century. The construction of that church has been linked to the royal court or a powerful local family. Hossmo is considered to have been the centre of a region in the late Iron Age or early Middle Ages. The church was probably built as a royal demesne or a church for a powerful leader.
However, in the conflict between Christianity and the old paganism, a wooden church was far too vulnerable, and was replaced by a stone church. This happened about 1120, and during the 13th century, the church was rebuilt with fortifications. Several written sources show that the church was used as garrison and flank defense for Kalmar during the Union conflicts in the early 16th century, Most of what we now see inside the church dates back to the 18th and 19th century. The belfry was completed in 1670.
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.
