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:
Ängsö Castle was first named as "Engsev" in a royal charter by king Canute I of Sweden (r. 1167-1196), in which he stated that he had inherited the property after his father Eric IX of Sweden. Until 1272, it was owned by the Riseberga Abbey, and then taken over by Gregers Birgersson.
From 1475 until 1710, it was owned by the Sparre family. The current castle was built as a fortress by riksråd Bengt Fadersson Sparre in the 1480s. In 1522, Ängsö Castle was taken after a siege by king Gustav Vasa, since its owner, Fadersson's son Knut Bengtsson, sided with Christian II of Denmark. However, in 1538 it was given by the king to Bengtsson's daughter Hillevi Knutsdotter, who was married to Arvid Trolle.
In 1710, the castle was taken over by Carl Piper and Christina Piper. Ängsö Castle was owned by the Piper family from 1710 until 1971, and is now owned by the Westmanna foundation. The castle building itself was made into a museum in 1959 and was made a listed building in 1965. It is currently opened to visitors during the summers.
The castle is a cubical building in four stores made by stone and bricks. The lower parts is preserved from the middle ages. It was redecorated and expanded in the 1630s. The 4th storey as well as the roof is from the expansion of Carl Hårleman from 1740-41. It gained its current appearance in the 1740s.
