St. Catherine's Monastery or the Dominican Monastery is a former monastery and one of the oldest buildings in Tallinn, the capital of Estonia. It is located in the heart of Tallinn's Old Town district full of warehouses and merchants' houses. Its remains constitute one of two remaining medieval monastery complexes in Tallinn.
A Dominican monastery is known to have existed at the site since at least 1246. The site, between present-day Vene and Müürivahe streets, was chosen carefully so as to facilitate both the friar's ability to preach to a large audience, and to suit their business interests, as they are known to have traded in fish. The monastery also had a brewery, producing four types of beer. Throughout the Middle Ages, the monastery was renowned for its scholarship.
In 1524, during the Reformation, the monastery was destroyed. Only fragments remain of the original complex. Parts have been incorporated into the Roman Catholic St. Peter and St. Paul's Cathedral, and other parts, including a finely carved portal, are visible via St. Catherine's Passage (Katariina käik), connecting Vene and Müürivahe streets.
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.
