Anyone who has read or seen Dan Brown's Angels and Demons remembers the scenes in Rome at the Pantheon.
Built more than 1800 years ago, the magnificent Pantheon building still stands as a reminder of the great Roman empire.
With its thick brick walls and large marble columns, the Pantheon makes an immediate impression on visitors. It was the largest dome in the world until 1436 when the Florence Cathedral was constructed.
At the top of the dome is a large opening, the oculus, which was the only source of light.
The front portico has three rows of 8 columns, each one with a diameter of 1.5m. A huge bronze door gives access to the cylindrical building. Its diameter equals the interior height of 43.3 meters.
The Pantheon now contains the tombs of the famous artist Raphael.
