Of the many wonderful ancient buildings in Rome, the Pantheon is the one that has remained virtually intact over thousands of years. There is no other building the size, age or scope of the Pantheon that has kept the integrity of its original design so well. You cannot discount this amazing power of preservation to luck It is clearly a phenomenal feat of engineering.

Many designers have copied and even equalled the amazing design of this building, but none have done better at introducing true innovation in architecture as the Pantheon did. This is even more phenomenal when you take into account that the building was designed in 125 AD under the Roman emperor Hadrian.
