The Pantheon was built as a temple to the gods of Olympus, was rebuilt by Emperor Hadrian between 118 and 128 BC after it was burned, but the real building that dates back to the initial age of Augustus.

At the beginning of 1300 the pantheon evolved into a Christian church called Santa Maria ad Martyres. In 27 BC was built by Agrippa Phanteon the friend of Augustus, he entrusted the construction a Luci Coccerio Aucto , and was decorated by the "Diogenes di Atene", then it was later burned and was restored under the power of Domitian, a few years later again suffered a destruction in the power of Traiano.

Through the conversion into a Christian church was saved by a lot of threats, to make clear that there was and remained the only case where a structure in the world of pagan worship was converted into a Christian structure.
