The Cathedral of Holy Wisdom in Polotsk was built by Prince Vseslav Briacheslavich between 1044-1066. It is first mentioned in the Voskresenskaia Chronicle under the year 1056. It is probably the oldest church in Belarus.
The cathedral is, like the Saint Sophia Cathedral in Kiev and Saint Sophia Cathedral in Novgorod, named after the Holy Wisdom of God. After building his own cathedral, Vseslav tried to seize the Kievan throne. Failing in that attempt, he raided the surrounding principalities; in 1067, he raided Novgorod the Great and looted the Cathedral of Holy Wisdom there, bringing a bell and other loot back to decorate his own Cathedral of Holy Wisdom. The cathedral is mentioned in The Tale of Igor's Campaign, where it says that Vseslav would make nocturnal trips to Kiev as a werewolf and would hear the bells of Holy Wisdom at Polotsk as they rang for matins.
The cathedral has been significantly rebuilt and heavily modified between the 11th and 18th centuries. Indeed, only parts of the church date back to the time of Vseslav, although the names of the builders are inscribed in a stone at the base of the cathedral: David, Toma, Mikula, Kopes, Petr, and Vorish. The burial vaults of 16 Polotsk princes dating back to the 11th century have been uncovered (indeed, Vseslav himself, said to have been a sorcerer as well as a werewolf, was buried in the cathedral he built). According to the Voskresenskaia Letopis (s.a. 1156), the cathedral originally had seven domes, later reduced to five after it was rebuilt following the fire of 1447.
During 1596–1654 and 1668–1839 church was a Greek-Catholic cathedral. It was rebuilt again in 1618–1620 by Greek-Catholic Archbishop St. Josaphat Kuntsevych following a fire in 1607, and again after a fire destroyed the cathedral and the city in 1643. In 1705–1710, Peter the Great and Aleksandr Menshikov used the church as a powder magazine; the magazine exploded. Over the next almost three decades (1738–1765), the Uniate archbishop, Florian Hrebnicki, rebuilt the cathedral. The Vilnius' architect Johann Christoph Glaubitz was responsible for the current appearance, which is an example of the Vilnius Baroque style. Currently it is a baroque structure with towers and the domes have been removed (or at least not rebuilt).
The cathedral housed a library and other important cultural artifacts, but the library was destroyed when King Stephen Báthory of Poland took the city during the Livonian War in the late 16th century. The town was also occupied by the French during the Napoleonic Invasion in 1812 (indeed, two battles were fought at Polotsk in August and October, the second seeing house-to-house fighting) and also during the Nazi Invasion in the 1940s during which a large number of inhabitants were slaughtered.
The cathedral has also changed functions several times over the centuries. With the Union of Brest, the cathedral became a uniate or Eastern Rite Catholic Church and remained as such until 1839 where Bishop Joseph Siemaszko terminated the union and restored the Belarusian Greek Catholic Church with the Russian Orthodox Church. During the Soviet period, the cathedral housed the Polotsk Regional State Archive (from 1949 to 1954). In 1967, restoration work took place as the cathedral was to be turned into a museum of atheism, but the museum was moved to Vitebsk in 1969. The cathedral is now part of the State Museum-Preserve of Polotsk and used as a concert hall with an organ.References:
The Castle of Gruyères is one of the most famous in Switzerland. It was built between 1270 and 1282, following the typical square plan of the fortifications in Savoy. It was the property of the Counts of Gruyères until the bankruptcy of the Count Michel in 1554. His creditors the cantons of Fribourg and Bern shared his earldom. From 1555 to 1798 the castle became residence to the bailiffs and then to the prefects sent by Fribourg.
In 1849 the castle was sold to the Bovy and Balland families, who used the castle as their summer residency and restored it. The castle was then bought back by the canton of Fribourg in 1938, made into a museum and opened to the public. Since 1993, a foundation ensures the conservation as well as the highlighting of the building and the art collection.
The castle is the home of three capes of the Order of the Golden Fleece. They were part of the war booty captured by the Swiss Confederates (which included troops from Gruyères) at the Battle of Morat against Charles the Bold, Duke of Burgundy in 1476. As Charles the Bold was celebrating the anniversary of his father's death, one of the capes is a black velvet sacerdotal vestment with Philip the Good's emblem sewn into it.
A collection of landscapes by 19th century artists Jean-Baptiste-Camille Corot, Barthélemy Menn and others are on display in the castle.
