The Tobolsk Kremlin was founded in 1587 when Moscow encouraged the construction of stone buildings in the city. In 1683-1686, masons sent from Moscow and Veliky Ustyug built the stone St. Sophia-Assumption Cathedral. Around the beginning of the 18th century the stone walls and the towers of the Kremlin were built, as well as a number of buildings that have not survived to our days, standing on a westward line from St. Sophia-Assumption Cathedral: the Holy Trinity Cathedral, the Bishop's House, the Holy Gate with the Church of St. Sergius of Radonezh and the bell tower. The Siberian Metropolitan Paul (who, before the appointment to Tobolsk, was the Archimandrite of the Chudov Monastery in the Moscow Kremlin) supervised the construction. The cathedrals built under his supervision were cross-domed structures topped by five domes.
At the end of the 17th century construction work in the Kremlin was continued by Semyon Remezov, a cartographer who was also the first historian of Siberia. He had the Departmental Palace (1699–1704) built above the southern cliff of the hill and the Trading Arcades (1702–1706) in the northwestern corner of the Kremlin.
Knyaz M. Gagarin, appointed in 1708 first governor of the Siberian province, planned to create in the Kremlin impressive buildings for military administrative and commercial use, which should have constituted, together with the Sofia court a monumental center. In construction works were employed Swedish prisoners of war who were in exile in Tobolsk. To prevent the erosion of the mountain, the Tobol River was moved to the south for two versts. In 1712, by the project of Remezov was built the stone tower Demetrius gate and next to it, on the edge of the mountain, the Ascension church (destroyed in 1717).
Despite the 1714 ban of stone construction, work continued until 1718. After the execution of governor Gagarin, the Demetrius gate remained unfinished. In 1743-1746 was built the Church of the Intercession, accessory building of St Sophia-Assumption Cathedral. Walls and towers were gradually destroyed. In 1799 were built the stone retaining walls of St. Sophia gully and a new multi-tier bell tower - the tallest building of the city.
In 1939 the Tobolsk Kremlin has been recognized architectural historical monument, subject to state protection. In 1952, it was revealed a progressive deterioration of masonry and drafted the plan of restoration work. In 1961, the Tobolsk museum received the status of Historical and Architectural Museum-Reserve.
In early 1970s there was the beginning of the restoration works. The walls and the towers were reconstructed.References:
The original Cochem Castle, perched prominently on a hill above the Moselle River, served to collect tolls from passing ships. Modern research dates its origins to around 1100. Before its destruction by the French in 1689, the castle had a long and fascinating history. It changed hands numerous times and, like most castles, also changed its form over the centuries.
In 1151 King Konrad III ended a dispute over who should inherit Cochem Castle by laying siege to it and taking possession of it himself. That same year it became an official Imperial Castle (Reichsburg) subject to imperial authority. In 1282 it was Habsburg King Rudolf’s turn, when he conquered the Reichsburg Cochem and took it over. But just 12 years later, in 1294, the newest owner, King Adolf of Nassau pawned the castle, the town of Cochem and the surrounding region in order to finance his coronation. Adolf’s successor, Albrecht I, was unable to redeem the pledge and was forced to grant the castle to the archbishop in nearby Trier and the Electorate of Trier, which then administered the Reichsburg continuously, except for a brief interruption when Trier’s Archbishop Balduin of Luxembourg had to pawn the castle to a countess. But he got it back a year later.
The Electorate of Trier and its nobility became wealthy and powerful in large part due to the income from Cochem Castle and the rights to shipping tolls on the Moselle. Not until 1419 did the castle and its tolls come under the administration of civil bailiffs (Amtsmänner). While under the control of the bishops and electors in Trier from the 14th to the 16th century, the castle was expanded several times.
In 1688 the French invaded the Rhine and Moselle regions of the Palatinate, which included Cochem and its castle. French troops conquered the Reichsburg and then laid waste not only to the castle but also to Cochem and most of the other surrounding towns in a scorched-earth campaign. Between that time and the Congress of Vienna, the Palatinate and Cochem went back and forth between France and Prussia. In 1815 the western Palatinate and Cochem finally became part of Prussia once and for all.
Louis Jacques Ravené (1823-1879) did not live to see the completion of his renovated castle, but it was completed by his son Louis Auguste Ravené (1866-1944). Louis Auguste was only two years old when construction work at the old ruins above Cochem began in 1868, but most of the new castle took shape from 1874 to 1877, based on designs by Berlin architects. After the death of his father in 1879, Louis Auguste supervised the final stages of construction, mostly involving work on the castle’s interior. The castle was finally completed in 1890. Louis Auguste, like his father, a lover of art, filled the castle with an extensive art collection, most of which was lost during the Second World War.
In 1942, during the Nazi years, Ravené was forced to sell the family castle to the Prussian Ministry of Justice, which turned it into a law school run by the Nazi government. Following the end of the war, the castle became the property of the new state of Rheinland-Pfalz (Rhineland-Palatinate). In 1978 the city of Cochem bought the castle for 664,000 marks.
