Previously, it was a circus that was the sporting and social centre of Constantinople, capital of the Byzantine Empire. The word hippodrome comes from the Greek hippos (ἵππος), horse, and dromos (δρόμος), path or way. For this reason, it is sometimes also called Atmeydanı ("Horse Square") in Turkish. Horse racing and chariot racing were popular pastimes in the ancient world and hippodromes were common features of Greek cities in the Hellenistic, Roman and Byzantine eras.

The Baths of Zeuxippus were popular public baths in the city of Constantinople, the capital of the Byzantine Empire. They were built between 100 and 200, destroyed by the Nika revolt of 532 and then rebuilt several years later. They were so called because they were built upon the site where a Temple of Zeus (Jupiter) had formerly existed. They were built around 500 yards south of the much older baths of Achilles of the earlier Greek Acropolis in Byzantion. The baths were famed primarily for the many statues that were built within, and the famous people they each represented. However, they were later used for military purposes, during the seventh century. Excavations of the site and the Baths were made in 1928.
