• Covered walkways over the dig lead down to the level of the palace floors, so the visit works in rain or summer sun
• Mostly wheelchair accessible, as most of the building is adapted for wheelchairs, which helps with a stroller too
• Arrive an hour before closing at the latest, as the site advises, to have time for the whole visit

The palace was built in the late 3rd or early 4th century for Roman emperors at Sirmium, the Roman city under today's Sremska Mitrovica. A modern building covers the dig, and walkways take visitors down among the excavated walls, the hot-air heating channels under almost every floor, and about 350 m² of geometric mosaic floors. Next to it lay the chariot-racing circus, the only Roman circus found in Serbia.
