The Pantheon has a dome that is made of concrete. The dome of the Pantheon is and always has been the largest unreinforced concrete dome in the world.

The Pantheon was made of stone, concrete, and over five different concrete mixtures. The dome had a heavier concrete mixture on the bottom, getting lighter as it got higher.

No. The Parthenon in Athens does not have a dome, but it may be confused with the Pantheon in Rome which does have a dome.

There are two striking characteristics of the pantheon. One is the large dome and the second is the oculus or opening in the top of the dome.

The architectural developments used in the pantheon were the use of the dome, (a perfect sphere) lighter concrete mixtures in the dome, and the use of coffers, or sunken panels in the dome to reduce the weight.

The Pantheon still has the largest reinforced concrete dome in the world. Some of the Roman temples were circular and had a dome, like the Pantheon. Knowledge of how to make Roman concrete was lost during he Middle Ages and domes were no longer built in western Europe for centuries. Then between 1446 and 1461 Brunelleschi built a dome for Florence Cathedral which was even bigger than that of the Pantheon. This was a big achievement because his dome is made with bricks. Brunelleschi had studied the dome of the Pantheon and other Roman architecture prior to his undertaking. Since then several churches and secular buildings (including the Capitol on Washington) have been built with domes. This was inspired by Roman architecture.

Its use of the cupola (dome) as a roof.

The ceiling of the Pantheon was dimpled "like a golf ball" to relieve stress from the dome.

The pantheon in Rome is 142 feet in diameter. The eye of the dome is 27 feet in length, and at its base, 26 feet thick.

There were actually two Roman buildings that used a dome. One was Nero's Golden House and the other was/is the Pantheon.

The Vatican, The Pantheon, The Colosseum, and St. Peter's Dome.

No, the oculus is associated with the Pantheon. It is the "eye" or hole in the ceiling of the dome.

The dome of Pantheon in Rome is made of roman concrete and it is still the largest unreinforced concrete dome in the word. It is the best-preserved of all Ancient Roman building in the city of Rome because it was tuned into a Christian church and thus it was maintained properly and was not ransacked for building materials. These days it is mainly as a tourist attraction.

The pantheon is unique because of its dome, oculus, size and longevity. But most importantly it is unique for its perfect proportions and the construction materials and method of using them.

The original Roman pantheon was built in the outskirts of Rome in an area which previously had a rural appearance but developed over a period of time. Being almost 2000 years old, It still has the world's largest dome built from unreinforced concrete.

The Pantheon in Rome has probably been on several coins. France made a coin with the Pantheon in Paris on it.

It is a dome, but the front side is unusally fronted by a row of columns supporting a pediment

The Pantheon may be the greatest achivement of roman engineering. Even today it is the largest single span dome in the world measuring 43 meters in diameter and 43 meters from the floor to the dome. If such a large dome id build today with modern concrete it would hardly stand its own weight, yet the Pantheon has stood for centuries.

The pantheon is important for several reasons, not the least is its being the oldest and best preserved Roman building in constant use.. It is a marvel of engineering, with its inner circle and height of the done being equal. It is the largest dome in the world of unreinforced concrete and is constructed with different weights of concrete in its dome.

The empty circle in the centre of the dome of the Pantheon, the oculus (eye) has two purposes. One is to let the light in. There are only two sources of light in the rotunda of the Pantheon: the entrance and the oculus, The other is to contribute to decreasing the weight of the dome. It is still the largest unreinforced concrete dome in the world. Nowadays there are domes which are bigger than that of the Pantheon. However, they are made of reinforced concrete. To manage to make such a large dome (its diameter is 43.3 metres, 142 ft.) with unreinforced concrete, its weight needed to kept to a minimum. If fact, this gigantic structure amazingly weighs only five tons. To achieve this, different types of aggregate were used. Roman concrete was made by mixing lime with a volcanic rock called pozzolana. This created a binder to which an aggregate was added to give it mass. The dome of the pantheon is 6.4 metres (21 ft.) thick at the bottom and crushed travertine rock was used as an aggregate. As it goes upwards, the dome becomes thinner and is 1.2 metres (3.9 ft.) thick at the top. Besides getting thinner, the aggregate changes. In the mid-section of the dome it is crushed terracotta tiles, which are lighter. In the top section it is made of crushed tuff and pomice, which are porous stones which are even lighter. Finally, the oculus makes the apex weightless. It has been calculated at without these weight-saving techniques the stresses on dome would be 80% higher and it would collapse under its weight. Roan concrete was a though as modern concrete, but it was less fluid and had to be layered by hand.

The Pantheon is famous for many reasons, the first being it dome. For many years it was the largest domed structure in the world. Other reasons are its age, its durability, it architecture and it's famous oculus.

Because much of it is made of or reinforced by a Roman invention - concrete (the most famous, extant example of which is the coffered dome of the Pantheon).See related links below.

You might be thinking of the Pantheon, however the Pantheon was more hemispherical and would not have worked on the scale of Brunelleschi's dome so he had to use newer Gothic methods.
