In
Roman city planning, a
decumanus was an east-west-oriented road in a
Roman city,
castra (military camp), or
colonia. The main decumanus was the
Decumanus Maximus, which normally connected the
Porta Praetoria (in a military camp, closest to the enemy) to the
Porta Decumana (away from the enemy).
This name comes from the fact that the via decumana or decimana (the tenth) separated the Tenth Cohort from the Ninth in the legionary encampment, in the same way as the via quintana separated the Fifth Cohort from the Sixth.
In the middle, or groma, the Decumanus Maximus crosses the perpendicular Cardo Maximus, the primary north-south road that was the usual main street. The Forum is normally located close to this intersection of the Decumanus Maximus and the Cardo Maximus.
Examples
In the ancient Roman city of
Barcino (present day
Barcelona, Spain), the Decumanus Maximus started at the Roman gate in front of the current
Plaça Nova square, which is the only Roman gate extant. In present day
Croatia within the city of
Split is the UNESCO Roman monument,
Diocletian's Palace. This city built by Emperor
Diocletian exhibits the characteristic Roman orthogonal street system with the Decumanus Maximus connecting the west
Silver Gate to the east Iron Gate. At the present day city of
Umm Qais,
Jordan, the decumanus is extant running east-west for approximately one kilometre with its ancient
flagstones extant; the name of this Roman city is
Gadara. Another fine example is the "Straight Street",
Via Recta in
Damascus, which is 1,500 metres long, connecting the eastern and western gates.
