Fehtija Mosque is a mosque and former Catholic church located in the town of Bihać, Bosnia and Herzegovina. Built in 1266, it is the oldest gothic building in the country. It was originally built as a Catholic church dedicated to Saint Anthony of Padua, and was subsequently transformed into a mosque following the 1592 conquest of Bihać from Habsburg Croatia by the Ottomans. The building was originally accompanied by a monastery, which was also mentioned in a 13th-century charter of the Croatian nobility.
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.
