Who built the Roman Pantheon?

In the time of the Roman Emperor Augustus, about 10 BC, one of his generals, a man named Agrippa, built a temple in the middle of downtown Rome “to all the gods“. A temple to all the gods is a Pantheon, which means “all gods” (pan= all, theon=of the gods, in Greek).

Now this temple was probably very fine, but we don’t really know, because in 80 AD, in the reign of Titus, it burned down in a fireDomitian built a new temple there, and THAT one burned down too.

Hadrian rebuilds the Pantheon

Around 120 AD Hadrian built a THIRD temple in the exact same place in a more modern style (modern for 120 AD anyway!). This is the temple we have today. But to honor Agrippa, Hadrian left a message over the door saying that Agrippa had built the temple, as you can see in the picture.

The inside of the Pantheon’s big concrete dome.

You might think, well, that doesn’t really look like much of a place. And from the outside it really doesn’t seem very impressive. The Pantheon is built like a Greek temple on the front, with eight columns across the front like the Parthenon, and a pediment on top of that.

Inside of the Roman Pantheon: the dome!

But on the INSIDE the Pantheon is one big giant dome, the largest dome ever built in the world up to that time – 43 meters in diameter (142 feet), and 43 meters from the floor to the top of the dome.

To hold up this dome, the builders had to make the brick and concrete six meters thick – about twenty feet! The coffering in the dome lightens it a little, but it’s still very heavy. Nobody built a dome anything like this size anywhere in the world until Hagia Sophia in Constantinople in the 500s AD (but even Hagia Sophia’s dome is still smaller than the Pantheon). The first dome that was bigger than the Pantheon was in the Duomo of Florence in the 1400s, more than a thousand years later. Even then, the Duomo dome is about the same size, and nobody ever built another one of that size, until the 1800s with reinforced concrete.

The hole in the top of the dome – the oculus– is open to the sky. Some people say the dome is so high that rain evaporates before it hits the floor, but that’s not true. Take it from me. I’ve lived in Rome in November, and on rainy days, the marble floor just gets wet.

The Pantheon becomes a Christian church

The first reason the Pantheon is in such good shape is that the Roman Emperor Phocas gave the building to the Popes in 609 AD for a Christian church, and the Popes since then have taken good care of it. And the second reason is that the Pantheon was a couple of miles away from where the great earthquake of 847 AD hit. So that earthquake wrecked the Colosseum and the Roman Forum, but not the Pantheon.

    Is it a church or what is it

    • Karen Carr April 30, 2018 at 8:37 am

      The Pantheon was built as a temple to the Roman gods – “Pan-theon” means “all the gods” – but when everybody in Rome decided to become Christians, they made the Pantheon into a Christian church, and it’s still a church today.

    hi why does this look like a Greek temple

    • Karen Carr April 17, 2018 at 9:51 pm

      It only looks like a Greek temple from the outside! That’s because the Romans got their ideas about how to build temples originally from the Etruscans, and the Etruscans got their ideas from the Greeks. But on the inside, it’s very different.

    Is this where jesus was assassinated?

    • Karen Carr April 17, 2018 at 8:28 am

      No; if you mean Julius Caesar, he was killed in the Theater of Pompey, which they were using as a temporary Senate House while the usual Senate House was being renovated.
