About: Decumanus (Roman city)
A decumanus (plural decumani) was the Latin name given to each of the east–west-oriented streets in a Roman city or castrum (military camp). In the rectangular street grid of the typical Roman city plan, the decumani were crossed by the perpendicular cardines, the north–south streets. The main, or central, decumanus was the Decumanus Maximus, or sometimes simply the Decumanus.
