The Great Lavra Bell Tower is the main bell tower of the ancient cave monastery of Kyiv Pechersk Lavra in Kyiv, the capital of Ukraine. It is one of the most notable buildings of the Kyiv skyline.
The bell tower was the highest free-standing bell tower at the time of its construction in 1731–1745. It was designed by the architect Johann Gottfried Schädel. Its total height, with the Christian cross, is 96.5 metres.
The Great Lavra Bell Tower is a Neoclassical architecture construction with a total of four tiers, surmounted by a gilded dome. The diameter of the tower's lowest tier at its base is 28.8 metres, and the thickness of the first tier walls is 8 metres. The tower is decorated with many architectural columns: the second tier is decorated with 32 Dorian columns, the third tier is decorated with 16 Ionic columns, and the fourth with 8 Corinthian columns.
On the third tier, there were some hanging bells, but they were later removed. To this day, only three small 18th-century bells have been preserved.
On the fourth tier there is a chiming clock, manufactured in 1903, which has a total weight of 4.5 tons. The current bell tower's clock, designed by the Moscow master A. Enodin and based on the Kremlin clock, replaced the older 18th-century clock of the master A. Levynskyi. The clock has stopped only once during its existence: it happened in September 1941 when the Dormition Cathedral of the Pechersk Lavra was blown up by army forces during the Second World War.
The clock was repaired following the destruction of the nearby cathedral, which took a total of six years to complete. Since that time, the clock has never needed any repairs. The clock's mechanism is very accurate; up to within 10 seconds. However, it has been observed that its accuracy depends on the time of the year: in the Winter, the clock works somewhat slower than in the Summertime. The clock's mechanism has to be rewound once a week, and the clock's bells chime every quarter of the hour.
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.
