Hippodrome is a term sometimes used for public entertainment venues of various types. A modern example is the Hippodrome which opened in London in 1900 "combining circus, hippodrome, and stage performances".
The term hippodroming refers to fraudulent sporting competitions, such as in racing or baseball.
The Hippodrome of Constantinople (Greek: Ἱππόδρομος τῆς Κωνσταντινουπόλεως, romanized: Hippódromos tēs Kōnstantinoupóleōs; Latin: Circus Maximus Constantinopolitanus; Turkish: Hipodrom) was a circus that was the sporting and social centre of Constantinople, capital of the Byzantine Empire. Today it is a square in Istanbul, Turkey, known as Sultanahmet Square (Turkish: Sultanahmet Meydanı).
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.
A Roman circus (from the Latin word that means "circle") was a large open-air venue used mainly for chariot races, although sometimes serving other purposes. It was similar to the ancient Greek hippodrome. Along with theatres and amphitheatres, circuses were one of the main entertainment venues at the time.
Similar buildings, called stadia were used for Greek-style athletics particularly in the eastern, Greek speaking, part of the empire, but these were typically smaller than circuses.
Roman amphitheatres are theatres — large, circular or oval open-air venues with tiered seating — built by the ancient Romans. They were used for events such as gladiator combats, venationes (animal slayings) and executions. About 230 Roman amphitheatres have been found across the area of the Roman Empire. Early amphitheatres date from the Republican period, though they became more monumental during the Imperial era.
Amphitheatres are distinguished from circuses and hippodromes, which were usually rectangular and built mainly for racing events, and stadia, built for athletics, but several of these terms have at times been used for one and the same venue. The word amphitheatrum means "theatre all around". Thus, an amphitheatre is distinguished from the traditional semicircular Roman theatres by being circular or oval in shape.
