Pažaislis monastery and church form the largest monastery complex in Lithuania, and the most magnificent example of Italian Baroque architecture in the country. Founded in 1662 by the Grand Duchy of Lithania Great Chancellor Krzysztof Zygmunt Pac for the Order of the Camaldolese Hermits, the main construction continued until 1674 and resumed in 1712. The church was designed by Pietro Puttini, Carlo and Pietro Puttini, and Giovanni Battista Frediani. In 1755 the addition of the towers and the dome was funded by the king's chamberlain Michał Jan Pac.
In 1832 the church was closed by the Russian authorities and later converted into an Orthodox church. The author of the Imperial Russian national anthem God Save the Tsar, Alexei Lvov, was interred there in 1870. After 1920 the ruined church returned to Roman Catholics and was restored by sisters of the Lithuanian convent of St. Casimir. After World War II, the Soviet authorities converted the church and monastery into an archive, a psychiatric hospital and finally an art gallery (in 1966). In 1990s the complex was returned to the nuns of the convent and reconstruction work began.
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.
