It was built in 203 AD by Emperor Septimius Severus. The origin of the name "Septizodium" is from Septisolium, from the Latin for temple of seven suns, and was probably named for the seven planetary deities (Saturn, Sol, Luna, Mars, Mercury, Jupiter, and Venus) or for the fact that it was originally divided into seven parts. The building had no known practical purpose and was probably meant to be a decorative façade, known as a nymphaeum. Ancient and medieval sources describe its purpose as being to impress Severus' fellow north Africans as they entered the city, as it was located at the place where the Via Appia passes the Palatine and leads east towards the Forum Romanum. Other examples of septizodia are known, all from Africa.

Ammianus Marcellinus refers to the building in an ambiguous passage: "The plebs...had come together at the Septemzodium, a popular place, where Marcus Aurelius built a Nymphaeum in a rather ostentatious style."
