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 Gravensteen is a castle in Ghent originating from the Middle Ages. The name means 'castle of the counts' in Dutch. Arnulf I (918–965), Count of Flanders, was the first to fortify this place, building a medieval bastion on this high sand dune, naturally protected by the river Leie and its marshy banks. This bastion consisted of a central wooden building and several surrounding buildings, also in wood.
In the early 11th century, the wooden building was replaced by a stone residence, consisting of three large halls that made up three storeys, connected by a stone stairwell. The monumental stone staircase, the light openings, the fireplaces built into the walls and the latrines were signs of considerable luxury and comfort in those days. There was probably also a tower.
