The Pantheon in Rome is one of the most widely respected works of architecture that has been preserved. The building is as old as 126 AD (it may be even older - that is the first record we have of it), and is so legendary that you will find imitations all around the world. It is a very popular tourist attraction, and it is easy to see why it is lauded and loved so much. It has immense historical value, and its high level of preservation and constant use have lead to it being internationally known. The building has been used as a church for St. Mary since the 7th century. You will find many imitators of the Pantheon all over the world. The Pantheon in Paris, for instance, was made in 1790 and has become an important historical site in its own right. Inspirations from the pantheon are seen in many buildings all around the world, generally educational institutes or government buildings. The arched interior of the Pantheon is grand and beautiful. We would highly recommend visiting this place if you're in Rome, as it is one of the must see sites of the city. We would recommend going here during the day as the 'Oculus' allows the light to enter the Pantheon in a special way, a marvelous feat of ancient engineering and ingenuity.
