The tsar’s residence in the Alexandrovskaya village (also known as the Alexandrovsky Kremlin) is an old Russian fortress which served as the actual capital of the oprichnina (the period of Russian history between 1565 and 1572 during which Tsar Ivan the Terrible instituted a domestic policy of secret police, massrepressions, public executions, and confiscation of land from Russian aristocrats) in the Moscow state from 1564 until 1581. Alexandrovskaya village dates back to the middle of the 14th century. Grand Duke Vasily III had a country palace built there and used to bring his family and the entire court to it. The palace did not survive.
The Pokrovsky cathedral was sanctified in 1513 and later it was blessed anew as the Trinity Cathedral. Its appearance has changed somewhat since the 16th century; some of the architectural details such as windows, e.g., belong to a later period. Originally, red brick and white stone were used in the outer decoration of the cathedral but brick parts were later painted over. Some of the interior fresco paintings date back to the 14th century as do the white stone carvings in the interior portals.
Ivan the Terrible moved to the Alexandrovskaya fortress in 1565. The residence was immediately fortified with a bulwark, wooden walls, and a moat. The village became the actual capital of the country. The oprichnina was founded there and the march on the Novgorod Republic started from the village.
As Novgorod was looted Ivan brought the famous gates of its St. Sophia Cathedral (1336) to the village and had them installed at the southern entrance of the Assumption (Trinity) cathedral. The gates combine religious and fantastic subjects; there is, for instance, the image of a centaur. The gates were made with the use of the old technique in which the door was first carved and then rubbed with a mixture of liquid gold and mercury.
The western entrance was embellished with the old (1344-1358) doors that Ivan had removed from the Transfiguration (Spaso-Preobrazhensky) church in Tver. An etched picture of the Holy Trinity is still preserved on one of the doors.
The Assumption nunnery was opened on its territory in the second half of the 17th century. During Soviet times the fortress and the former nunnery were used as a museum. At present, the territory of the Kremlin is shared by a museum and the revived nunnery.
References:The Clementinum is a historic complex of buildings in Prague. Until recently the complex hosted the National, University and Technical libraries, the City Library also being located nearby on Mariánské Náměstí. The Technical library and the Municipal library have moved to the Prague National Technical Library at Technická 6 since 2009. It is currently in use as the National Library of the Czech Republic.
Its history dates from the existence of a chapel dedicated to Saint Clement in the 11th century. A Dominican monastery was founded in the medieval period, which was transformed in 1556 to a Jesuit college. In 1622 the Jesuits transferred the library of Charles University to the Klementinum, and the college was merged with the University in 1654. The Jesuits remained until 1773, when the Klementinum was established as an observatory, library, and university by the Empress Maria Theresa of Austria.
