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:Rosenborg Palace was built in the period 1606-34 as Christian IV’s summerhouse just outside the ramparts of Copenhagen. Christian IV was very fond of the palace and often stayed at the castle when he resided in Copenhagen, and it was here that he died in 1648. After his death, the palace passed to his son King Frederik III, who together with his queen, Sophie Amalie, carried out several types of modernisation.
The last king who used the place as a residence was Frederik IV, and around 1720, Rosenborg was abandoned in favor of Frederiksborg Palace.Through the 1700s, considerable art treasures were collected at Rosenborg Castle, among other things items from the estates of deceased royalty and from Christiansborg after the fire there in 1794.
Soon the idea of a museum arose, and that was realised in 1833, which is The Royal Danish Collection’s official year of establishment.
