Mariastern Abbey is a Trappist abbey in Bosnia and Herzegovina, situated near the country's second largest city Banja Luka. It was founded in 1869 by trappist Franz Pfanner. It consists of the Church of the Assumption of the Blessed Virgin Mary (1873) and the monastery of Trappist monks. It is the only Trappist monastery in Southeastern Europe. At the beginning of the 20th century, with 219 monks, the Abbey was the largest Trappist abbey in the world; today it is the smallest, with only two monks.
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.
