The ancient Roman name of Ljubljana was Emona. Today one can still see some Roman elements in the city. E.g. this redesign of a part of the Roman town walls created by architect Jože Plečnik. The reconstruction of the walls is not really authentic but works as remarkable monument to the former presence of the Romans.
By the way, the boundary between original Roman wall and reconstructed wall is marked by a thin line of small stones.
