The Allenburg Church is a Brick Gothic building established near Allenburg Castle by Konrad von Jungingen, the Grand Master of the Teutonic Knights, in 1405. Seriously damaged during the First World War, the medieval building was restored and slightly expanded in 1925. After the Second World War, Allenburg was renamed Druzhba. It is now part of Pravdinsky District of Kaliningrad Oblast. The church was used by local farmers as a grain-drier. It was restored by the local Lutheran community in 2005 and eventually passed to the Russian Orthodox Church in 2010.
References:Visby Cathedral (also known as St. Mary’s Church) is the only survived medieval church in Visby. It was originally built for German merchants and inaugurated in 1225. Around the year 1350 the church was enlarged and converted into a basilica. The two-storey magazine was also added then above the nave as a warehouse for merchants.
Following the Reformation, the church was transformed into a parish church for the town of Visby. All other churches were abandoned. Shortly after the Reformation, in 1572, Gotland was made into its own Diocese, and the church designated its cathedral.
There is not much left of the original interior. The font is made of local red marble in the 13th century. The pulpit was made in Lübeck in 1684. There are 400 graves under the church floor.
