Septizodium

"The Septizodium was a three-tiered nymphaeum (a monumental fountain) built by the Roman emperor Septimius Severus in the early 3rd century AD. It was located on the Palatine Hill in Rome, and was visible to travelers arriving on the Via Appia. The Septizodium was named for its seven exedrae (niches), which were decorated with statues and fountains. It is thought that the exedrae were dedicated to the seven planetary deities: Saturn, Jupiter, Mars, Mercury, Venus, the Sun, and the Moon. The Septizodium was a popular tourist attraction in its time, and was mentioned by several Roman writers, including Ammianus Marcellinus and Cassiodorus. However, it fell into disrepair after the fall of the Western Roman Empire, and was eventually demolished in the 16th century. Today, only the foundations of the Septizodium remain. However, there are several Renaissance drawings and paintings that depict the monument, which give us an idea of what it once looked like. "
