The Ara Coeli Insula is a rare example of a rented house from the Imperial era. The term insula originally indicated a single house surrounded by an open space. At the end of the Republic, the word referred to a rented house, while a domus was used for home ownership, with an atrium and a peristyle. The need for housing for the growing population of Rome and the shortage of land for building led them to construct buildings with vertical development.

The building was discovered during the work in 1926 on the isolation of the Capitol and four complete floors and the remains of the other two are preserved. Unfortunately the entire facade is not currently visible because the ground floor and first floor are about 9 meters below the current street level.

It is estimated that the insula housed about 380 people.
