6 July-18 Nov. Under the subheading Il Limes danubiano – Da Traiano a Marco Aurelio, this interactive exhibition at Trajan's Markets focuses on the frontiers of the Roman empire.

The so-called Roman Limes, recognised officially by UNESCO in 2015, represent the border line of the Roman Empire at its greatest extent in the 2nd century AD.

The exhibition includes video and documents relating to the Roman fortresses, military camps, villages, sanctuaries, burial areas, ports and roads along the Danubian Limes whose territory corresponds to the modern-day Slovakia, Germany, Austria and Hungary.
