In 1632 the future Patriarch Nikon attempted to escape from the Solovki to the Kozheozero Monastery in the south. As Nikon later recalled, a tempest broke out and his life was at peril. The monk began to pray to the holy cross and soon his boat was cast a shore on Kiy Island, where he erected a wooden cross to thank heaven.
Twenty years later, he went from Novgorod to the Solovki in order to bring the relics of Metropolitan Philip to Moscow. On his way he visited Kiy-Island and was pleased to see his wooden cross still standing. Upon becoming the Patriarch a year later, Nikon ordered a monastery to be established on the spot. The monastery was dedicated to the True Cross in 1656, whereupon 4537 peasants were declared its property.
Under Nikon's supervision, the Krestny Monastery became one of the richest in the region. The patriarch sent to the monks a huge cypress cross, commissioned by him in Palestine as 'an exact replica of the True Cross' and lavishly decorated with jewels. In 1660 he visited the monastery for the last time and dwelled there for a year. It is believed that the wayward patriarch personally selected the location of and designed most buildings to suit his taste. It was for his own use that a singular choir loft was built within the cathedral. A large portion of monastery buildings, including the cathedral, were constructed from local granite, to be in harmony with the rocky setting.
After Nikon's fall from grace, the monastery declined and its possessions were expropriated. The British Royal Navy sacked the island during the Crimean War on 9 July 1854. The following year it was damaged by fire but the Holy Synod decided in favour of restoring the complex. The Communists disbanded the abbey in 1922.
The granite heights of the island are crowned by the four-pillared Cathedral of the Exaltation of the Cross, dedicated in the presence of Nikon on 4 September 1661. Its monumental proportions are deliberately archaic but the overall effect is unusually spacious and light for traditional Russian architecture. There were formerly three domes but only the central one still subsists. Other buildings from Nikon's period include the chapel over the well (1661), the two-storey refectory church of the Virgin's Nativity (1689), the sadly disfigured All Saints Church (1661), and various outbuildings.
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.
