The Vallis Murcia was the Latin name of a valley in the city of Rome between the Palatine and the Aventine Hill, where the Circus Maximus was sited.
[1] It was historically significant as a communication route and a neutral place of assembly for events, ceremonies, and performances involving harvest, trade, and military exercises.
[2] The valley was particularly associated with activities of the plebs and also those bridging the patrician and plebeian divide.
[1] It was formed from a stream that issued from the east and headed toward the Tiber River.
Diane Favro has described the topography: Carved out by this stream descending from the eastern plateaus, the valley is defined by the sharp slopes of the Palatine Hill on the north and those of the Aventine Hill on the south.
