Basilica Aemilia, Rome

Basilica Aemilia, Rome

When the Romans had any activity they wanted to do in groups, but inside, out of the weather, they generally met in a basilica (ba-SILL-uh-ka). A basilica is a long hall with two or more rows of columns running down the long way to help hold the roof up, like many churches today. Like churches today, basilicas often had a rounded apse. Most Roman basilicas had the doors on the long side, though.

This is the ruins of a Republican basilica, the Basilica Aemilia, in the Roman Forum, with the Roman Senate House and the Arch of Septimius Severus in the background.

The inside of a basilica was basically a lot like a modern Christian church or a medieval cathedral: a big hall with columns down the sides to make aisles, as you can see in this picture of the Basilica Aemilia. Sometimes they had a raised platform at one end for the important people to sit on. The floor of the Basilica Aemilia was built of many different kinds of marble, that came from Numidia and Egypt in Africa, from Greece, and so forth, to show all the different places that the Roman Empire ruled.

Basilica Julia, Rome

Basilica Julia, Rome

This is the ruins of another basilica, the Basilica Julia, on the other side of the Roman Forum. (The temple of Castor and Pollux is in the foreground, and the Column of Phocas is on the left). The Basilica Julia was built in the time of the Emperor Augustus, at the beginning of the Roman Empire, and named after Julius Caesar. Can you see the front steps, the side aisles, and the middle wide nave?

One difference from medieval or modern churches is that people usually went into a Roman basilica through a door in the middle of the long side, instead of on the short side.

Inside the basilica, judges heard court cases, or politicians made speeches, or sometimes teachers held classes. Outside, on the steps of the basilica, people sold food or changed money in little booths. When the Basilica Aemilia burned down, some of the money-changers spilled their bronze coins and the fire melted the coins into the marble floor. You can still see them there today.

About 100 AD,  the Roman emperor Trajan added a new forum in Rome. It had a new basilica, the Basilica Ulpia (in the background you can see the Column of Trajan; the Markets of Trajan are off to the right).

Basilica of Maxentius and Constantine - Roman forum

Basilica of Maxentius and Constantine – Roman forum

In the late empire, about 310 AD, the Emperor Maxentius built a new basilica at the other end of the Roman Forum, which was finished by Constantine. This is called the Basilica of Maxentius and Constantine. This basilica was absolutely enormous. But also, it was one of the first basilicas to have its doors on the short side instead of the long side, even though it was not a church.

When Christians started to build churches in the 200s AD, they didn’t want them to look like temples. And anyway, they needed a different kind of space, where a group of people could meet and hear each other talk. So the Christians built their churches like basilicas. After Constantine converted to Christianity, many Christian churches, like Chartres Cathedral or the Duomo in Florence, were built using variations on the basilica form.
