Cardus MaximusCardus Maximus
is a term in ancient Roman city planning. It denotes a N-S oriented road in a Roman military camp or colonia
. The main cardus is the Cardus Maximus. In the middle the Cardus Maximus crosses the perpendicular Decumanus Maximus
, the other main road. The Forum
is normally located at this intersection of the Decumanus Maximus and the Cardus Maximus.
The term 'cardus' is derived from the N-S line the augurs would draw when making the auspices.
