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:Celje Castle was once the largest fortification on Slovenian territory. The first fortified building on the site (a Romanesque palace) was built in the first half of the 13th century by the Counts of Heunburg from Carinthia on the stony outcrop on the western side of the ridge where the castle stands. It had five sides, or four plus the southern side, which was a natural defence. The first written records of the castle date back to between 1125 and 1137; it was probably built by Count Gunter. In the western section of the castle, there was a building with several floors. Remains of the walls of this palatium have survived. In the eastern section, there was an enclosed courtyard with large water reservoirs. The eastern wall, which protects the castle from its most exposed side, was around three metres thicker than the rest of the curtain wall. The wall was topped with a parapet and protected walkway.
