The Pantheon is an ancient temple in Rome that was dedicated to all the gods of the seven planets. In fact, Pantheon in Latin means" temple of all gods". It is the most complete building of Ancient Rome that still exists. The original pantheon was built in 27BC., but due to a huge fire, most of the buildings were destroyed along with the pantheon.
The pantheon building which we see today was actually reconstructed in 125Ad, during the reign of the Emperor Hadrian. The entrance is a great portico of columns. The main building is huge and round. with an immense dome that was built of concrete. The dome has a central opening or oculus, which is open to the sky. The most amazing thing about the pantheon is that the height to the oculus and the diameter of the interior circle are the same. The pantheon is one of the greatest tourist attractions in the world today.
