All roads lead to the grain market
In most cities we can find a main square which is the meating point of important routes - streets which grow out of roads. But hardly any square of that type can be compared to the Grain Square of Karlovac: it was close to the port on the river Kupa and its streets led to Slovenia, Zagreb, Croatian primorje, Lika and Bosnia. Of special importance was the grain supply from the wider Danubian hinterlands to Italy through the sea ports.
In Karlovac, grain was reloaded from boats to horse-drawn carriages and directed towards Rijeka and Bakar along roads called Karolina and Lujzijana, and towards Senj along a road called Jozefina.
