The Pantheon, in Rome.

A text, in english, from Wikipedia, the free encyclopedia:
Pantheon, Rome.
The Pantheon (Latin: Pantheon, from Greek: ????????, meaning "Temple of all the gods") is a building in Rome which was originally built as a temple to all the gods of Ancient Rome, and rebuilt circa 126 AD during Hadrian's reign. The intended degree of inclusiveness of this dedication is debated. The generic term pantheon is now applied to a monument in which illustrious dead are buried. It is the best preserved of all Roman buildings, and perhaps the best preserved building of its age in the world. It has been in continuous use throughout its history. The design of the extant building is sometimes credited to Trajan's architect Apollodorus of Damascus, but it is equally likely that the building and the design should be credited to Emperor Hadrian's architects, though not to Hadrian himself as many art scholars once thought. Since the 7th century, the Pantheon has been used as a Roman Catholic church. The Pantheon is the oldest standing domed structure in Rome. The height to the oculus and the diameter of the interior circle are the same, 43.3 metres (142 ft).
n the aftermath of the Battle of Actium (31 BC), Agrippa built and dedicated the original Pantheon during his third consulship (27 BC). Agrippa's Pantheon was destroyed along with other buildings in a huge fire in 80 AD. The current building dates from about 126 AD, during the reign of the Emperor Hadrian, as date-stamps on the bricks reveal. It was totally reconstructed with the text of the original inscription ("M·AGRIPPA·L·F·COS·TERTIVM·FECIT", standing for Latin: Marcus Agrippa, Lucii filius, consul tertium fecit translated to "'Marcus Agrippa, son of Lucius, Consul for the third time, built this") which was added to the new facade, a common practice in Hadrian's rebuilding projects all over Rome. Hadrian was a cosmopolitan emperor who travelled widely in the East and was a great admirer of Greek culture. He might have intended the Pantheon, a temple to all the gods, to be a kind of ecumenical or syncretist gesture to the subjects of the Roman Empire who did not worship the old gods of Rome, or who (as was increasingly the case) worshipped them under other names. How the building was actually used is not known.
Cassius Dio, a Graeco-Roman senator, consul and author of a comprehensive History of Rome, writing approximately 75 years after the Pantheon's reconstruction, mistakenly attributed the domed building to Agrippa rather than Hadrian. Dio's book appears to be the only near-contemporary writing on the Pantheon, and it is interesting that even by the year 200 there was uncertainty about the origin of the building and its purpose:
Agrippa finished the construction of the building called the Pantheon. It has this name, perhaps because it received among the images which decorated it the statues of many gods, including Mars and Venus; but my own opinion of the name is that, because of its vaulted roof, it resembles the heavens. (Cassius Dio History of Rome 53.27.2)
The building was repaired by Septimius Severus and Caracalla in 202 AD, for which there is another, smaller inscription. This inscription reads "pantheum vetustate corruptum cum omni cultu restituerunt" ('with every refinement they restored the Pantheon worn by age').
In 609 the Byzantine emperor Phocas gave the building to Pope Boniface IV, who converted it into a Christian church and consecrated it to Santa Maria ad Martyres, now known as Santa Maria dei Martiri.
The building's consecration as a church saved it from the abandonment, destruction, and the worst of the spoliation which befell the majority of ancient Rome's buildings during the early medieval period. Paul the Deacon records the spoliation of the building by the Emperor Constans II, who visited Rome in July 663:
Remaining at Rome twelve days he pulled down everything that in ancient times had been made of metal for the ornament of the city, to such an extent that he even stripped off the roof of the church [of the blessed Mary] which at one time was called the Pantheon, and had been founded in honor of all the gods and was now by the consent of the former rulers the place of all the martyrs; and he took away from there the bronze tiles and sent them with all the other ornaments to Constantinople.
Much fine external marble has been removed over the centuries, and there are capitals from some of the pilasters in the British Museum. Two columns were swallowed up in the medieval buildings that abbutted the Pantheon on the east and were lost. In the early seventeenth century, Urban VIII Barberini tore away the bronze ceiling of the portico, and replaced the medieval campanile with the famous twin towers built by Maderno, which were not removed until the late nineteenth century. The only other loss has been the external sculptures, which adorned the pediment above Agrippa's
