the basilica of Saint John Lateran was built under pope Melchiade (311-314). It is the oldest surviving church in the world. Due to the fact that the pope is also the bishop of Rome, Saint John in Lateran is also Rome's Cathedral.
The present structure of the Basilica resembles the Saint Peter's basilica. The original plan had already five aisles. The ancient church was residence of the popes until the coming back from the exile in Avignone (1377), when it was moved to the Vatican. It was pillage-stock of the Visigoths (410), the Vandals (455); the earthquake in 896 caused the central aisle roof to collapse (rebuilt under pope Sergio III in 904-911).
Put on fire in 1308 first and in 1361 then, it was remade under the pontificate of Gregorio XI (1370-1378), following the plan of the ancient structure that had by then become a ruin. The repair works continued during the entire fifteenth century and the sumptuous ceiling was realized in 1562.
Sisto V (1585-1590) ordered the construction of the Blessings Lodge (positioned at the end of right side aisle), and the making of the Lateranense building assigning the project to Domenico Fontana.
After about 140 years Pope Innocenzo X Pamphili (1644-1655) decided in 1646 to bring the cathedral to new splendour entrusting Francesco Borromini of the repair. The architect was supposed to finish the works in time for the Holy Year of 1650 and had to reserve (according to the pacts with the pope) the structure of the ancient Basilica of St John Lateran. The artist put 12 niches spaced up by 5 huge arches supported by as many pillars in the mid aisle.
The great statues of the Apostles that we can admire today in the borrominian niches were made by sculptors of the late baroque in the beginning of 1700.
In 1731 Pope Clement XII summons a competition for the new façade of Saint John in Lateran. The winner without too much merit was the Florentine Alessandro Galilei who in 1735 finishes the works of the present façade. Under the ogival tabernacle (at the end of the central aisle, in the transept) is the papal altar where only the Pope can give mass. Above the sacramental altar there's a fragment of the table on which Jesus consumed the last supper. The Cathedral hosts also Jesus' blood, brought to Rome by centurion Longino. Numerous are the chapels of noble families realized by some of the best artists of the different epochs. In the intermediate right aisle, close to the first pillar, one can admire Boniface VIII proclaims the Jubilee of 1300, a fresco made by Giotto.
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.
