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:
Sirmione castle was built near the end of the 12th century as part of a defensive network surrounding Verona. The castle was maintained and extended first as part of the Veronese protection against their rivals in Milan and later under the control of the Venetian inland empire. The massive fortress is totally surrounded by water and has an inner porch which houses a Roman and Medieval lapidary. From the drawbridge, a staircase leads to the walkways above the walls, providing a marvellous view of the harbour that once sheltered the Scaliger fleet. The doors were fitted with a variety of locking systems, including a drawbridge for horses, carriages and pedestrians, a metal grate and, more recently, double hinged doors. Venice conquered Sirmione in 1405, immediately adopting provisions to render the fortress even more secure, fortifying its outer walls and widening the harbour.
Thanks to its strategical geographical location as a border outpost, Sirmione became a crucial defence and control garrison for the ruling nobles, retaining this function until the 16th century, when its role was taken up by Peschiera del Garda.
