The Roman circus of Mérida is a Roman circus in the Roman colonia of Emerita Augusta –present-day Mérida, Spain–, capital of the Roman province of Lusitania. Used for chariot racing during ancient Rome, it was modelled on the Circus Maximus in Rome and other circus buildings throughout the Empire. Measuring more than 400 m (1,300 ft) in length and 30 m (98 ft) width, it could house up to 30,000 spectators. Although currently in ruins, it is one of the best preserved examples of Roman circus.
