The Pantheon is one of the most recognizable buildings in the heart of Rome, Italy. Built by Agrippa between 27 and 25 BC, the Pantheon was a temple dedicated to twelve gods and to the living Sovran.
Traditionally, it is believed that the present building is the result of a radical reconstruction by Hadrian between 118 and 125 AD.
It is the only ancient Roman building that has remained practically intact through the centuries.
In 608, Pope Boniface IV had the remains of many martyrs removed from the Christian catacombs and placed in the Pantheon.
