Holy Spirit Cathedral was built in Baroque style between 1633-1642 as the main temple of Catholic Bernadine convent. During the 1700-1800s it was reconstructed to the present architectural shape. In 1852 the convent was closed, and its nuns were sent to Nesvizh town. In I860 the former monastic church was turned into the orthodox church. After ten years an orthodox monastery was opened here.
In 1918, after the closing of the monastery, the building was used for various purposes: as a sports hall, a transit prison for the dispossessed peasants. The services were renewed during World War II, in 1943. The most valuable relic is the wonder-working icon of Mother of God found in 1500. The other relic of the temple is imperishable relics of St. Sofia of Slutsk, a grand daughter of Anastasia of Sluck.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.
