On the eastern side of Cathedral Square stands the magnificent Ivan the Great Belltower, which, at a height of 81 metres, was the tallest building in all Russia for almost 400 years. It was the work of an Italian, Marco Bono, who was ordered by Ivan the Great to design a belltower for the Archangel, Assumption and Annunciation Cathedrals next to the 1329 Church of St. John Climacus-under-the Bells.
Between 1532 and 1543, architect Petrok Maliy built the four-storey Assumption Belfry, which stands next to the tower and houses the 64-ton Resurrection Bell, cast in the 19th Century. In 1624, the tent-roofed Filaret Tower was added.
In 1812, Napoleon's soldiers tore down many of the buildings of the Kremlin, and attempted to blow up the bell tower. Thankfully they failed, although the belfry and the Filaret Tower were badly damaged. They were restored in 1819 by the architect D.I. Gilardi.
There are 21 bells in the tower and belfry, of which the Assumption Bell, located in the central arch of the belfry, is the largest at 70 tons. It was always the first bell to ring on church holidays, a signal that started all the other church bells in Moscow. In 1918 the last Easter service in the Kremlin took place, and the bells of Ivan the Great did not ring again until 1992.
Wide scale restoration work was carried out in the 1950s, and an exhibition hall was created on the ground floor, which is still used for various temporary exhibitions.
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.
