Many buildings have been built throughout history, but most of them not remain. Some of them changed the course of history. They did this with their architecture, or with the importance attributed to them, or with their witness to the history. All these structures had great effects. Architecture is a field for reflection of human desires and thoughts, wishes or passions just like other branches of art. However it is a field of art that is much more influential and has visible touches on human life. The architecture of Pantheon in ancient Rome was a good example for this impact. It has made the building one of the symbolic structures of absolute power and divine devotion.
Just like Hagia Sophia, the Pantheon building, which has maintained its influence and existence for ages and has served as a sacred temple for societies, is the most technological structure of its period.
The History of Pantheon Architecture
A temple was built in Rome in 27 BC. When this temple was destroyed, Emperor Hadrian had the Pantheon Temple built in 118 AC, which is still standing today. Considering the period in which it was built, Pantheon was probably built in the most glorious period of Rome. Hadrian is famous for building the largest and mightiest buildings of the ancient Roman architecture era. He built huge baths, amphitheatres, triumphal arches and temples in order to spread his glory and power to wide geographies. The Pantheon located in Rome, on the other hand, is a product of Hadrian’s passion in the field of religious structure.
Earlier temples were often built in dedicated to a god or goddess. For instance, the Parthenon of Athens or the Temple of Zeus are one of them. However, the Pantheon was dedicated to all gods believed in Rome. As its very name signifies, Pan(All)-theon(god) in Greek means “Temple of All Gods”. An ordinary temple should not have been built for such a great honor. The Pantheon structure, the most magnificent temple ever built, contains a lot of technological innovations for the period it was built.
After the Romans accepted Christianity, some old pagan temples were converted into churches. The Pantheon of Rome got its share from this transformation in the 7th century under the name of Santa Maria Rotonda. Due to this function change, a bell tower was added to each side of the triangular pediment of the building. However, these towers do not exist today.

- The most striking feature of the ancient Roman Pantheon is undoubtedly the hole in the middle of the dome called the Oculus. This Pantheon oculus hole is 6 meters in diameter. When we look at the up, we encounter a dizzying ceiling beauty accompanied by the light leaking through the hole.
- It is possible to place a sphere in contact with the floor, the Oculus and the side walls in the interior of the Pantheon, which has a central plan. Because the height of the dome from the ground and the inner width of the body part are equal to 43 meters.
- In order to carry the 43-meter-diameter dome, the Romans applied the concrete, which they skillfully used, with a special technique. According to this, as it go up to the top of the Pantheon dome, the aggregate mix in the concrete gets lighter. In this way, the unit weight of the concrete, which is the essential material of the dome, was at the lowest level near the Oculus (Wilkinson).
- Until the 55.6-meter-high dome of Hagia Sophia was built, the highest dome belonged to the Pantheon. Additionally, it has one of the largest domes in the world still.
