Dedicated to a cult worshipping all the gods (as demonstrated by the etymology of the name itself consisting of “Pan” – all and “Theon” – gods, the Pantheon was built under Emperor Hadrian between 118 and 125 AD on the ruins of an already existing temple.
One of its main features is its almost perfect shape. The structure can in fact be inscribed within a perfect sphere with the height being perfectly equal to its diameter (43,44 m by 43,44 m).
At the beginning of the seventh century, the Pantheon was converted into a Christian basilica by the name of Santa Maria della Rotonda.
The interiors and exteriors are recognised by the painstaking attention to detail, for the excellent marbles and other materials used as well as for the decorations used.
