The great Insula of the capitol, in its environment, in the centre right of the picture. The “block” of the capitol was comprising six storeys : shops at the ground level with an entresol, balconies on the first floor.

The great Insula was built at the foot of the Capitol, which you can see upper right on the picture. In the foreground the Theatre of Balbus.

It’s under Augustus that these high rental buildings began to be built, often badly built and dangerous. In vain, the Emperor Trajan tried to control the construction of these multiple storey buildings. The most famous of the Insulæ, true touristic attraction due to its height, was the Insula Felicles, the building of Felicula, that might have stood between the Pantheon and the Aurelian column, in the IXth region.
