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 ancient Argos Theater was built in 320 BC. and is located in Argos, Greece against Larissa Hill. Nearby from this site is Agora, Roman Odeon, and the Baths of Argos. The theater is one of the largest architectural developments in Greece and was renovated in ca 120 AD.
The Hellenistic theater at Argos is cut into the hillside of the Larisa, with 90 steps up a steep incline, forming a narrow rectilinear cavea. Among the largest theaters in Greece, it held about 20,000 spectators and is divided by two landings into three horizontal sections. Staircases further divide the cavea into four cunei, corresponding to the tribes of Argos A high wall was erected to prevent unauthorized access into the theatron and may have helped the acoustics, but it is said the sound quality is still very good today.
Around 120 CE, both theaters were renovated in the Roman style.
