Novgorod Kremlin (Detinets) stands on the left bank of the Volkhov River. It is part of the UNESCO World Heritage Site of Historic Monuments of Novgorod and Surroundings. The compound was originally the site of a pagan burial ground upon which the first bishop of Novgorod, Ioakim Korsunianin built the Cathedral of Holy Wisdom upon his arrival in the area in 989 or so. Thus the compound was and remained largely an ecclesiastical site, although many Novgorodian boyars built their houses in the southern part of the Detinets.
The first reference to fortifications on the site dates to 1044, with additional construction taking place in 1116. These were probably earthen embankments topped by a wooden palisade, although stone towers and walls were built in 1302. Archbishop Vasily Kalika (1330–1352) rebuilt the stone wall along the eastern side of the Detinets in 1331-1335. The rest was completed in stone only in 1400. Part of Vasily"s walls collapsed into the Volkhov River in 1437 and were rebuilt by Archbishop Evfimy II (1429–1458).
The current fortress was built between 1484 and 1490 by Muscovite builders in the wake of Grand Prince Ivan III"s conquest of the city in 1478; a third of it was paid for by the Novgorodian archbishop Gennady, a Muscovite appointee (1484–1504). It is a large oval 545 meters long and 240 meter wide with nine surviving towers (three additional towers have not survived). The tallest tower, the Kokui tower is capped by a silver dome. It was built in the eighteenth century and its name is of Swedish origin. Today it is possible to enter this tower and climb to the top. The walls are 1,487 meters in circumference.
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.
