The Kastamonitou Monastery, officially called Konstamonitou, is an Orthodox Christian monastery in the monastic state of Mount Athos in Greece. It stands on the southeastern side of the Athos peninsula. The monastery ranks twentieth and last in the hierarchy of the Athonite monasteries.
The monastery was founded in the mid-11th century, either by an unknown member of the aristocratic Byzantine Kastamonites family, or by an unrelated person hailing from the area of Kastamon in Paphlagonia. It is dedicated to Saint Stephen. Its history during the Byzantine period is obscure, and until the 14th century it appears to have been a moderate establishment. After it was destroyed in a fire in the 1420s and restored by the Serbian magnate Radič, it attracted many monks from the South Slavic lands, and experienced a century of prosperity.
The monastery's present buildings date to the 18th and 19th centuries. The monastery has about 20 working monks. The monastery library holds 110 manuscripts and approximately 5,000 printed books.
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.
