Regio XI Circus Maximus

Regio XI took its name from the Circus Maximus, located in the valley between the Palatine and the Aventine hills.

Regio XI was dominated by the feature from which it derived its name, the Circus Maximus, Rome's largest venue for ludi (or public games) connected to Roman religious festivals.

[1] Apart from the Circus itself, the largest in the city of Rome, according to the 5th century Notitia this region contained temples dedicated to the Sun, the Moon, Cerces, Dīs Pater (the Roman god of the Underworld), Magna Mater and Mercury.

[2] The main street in this region was the Clivus Publicus which led from the Circus to the Aventine where it encountered the Porta Trigemina.

[3] At the turn of the 5th century, the Regio was divided into 19 vici (districts) and 2,600 insulae (blocks).
