A Roman settlement, Aquae Iasae, was established between 1st and 4th centuries AD in the vicinity of the hot springs in Varaždinske Toplice. Already during the systematic archaeological research, undertaken on this site since 1953 by the Antiquity Department of the Archaeological Museum in Zagreb, a Roman public complex was discovered that includes the thermae, composed of public baths and a basilica, and temples surrounding the hot springs.
The most recent archaeological explorations, dating from 2011–12, revealed innovative construction solutions, while numerous finds of stone monuments, reliefs, inscriptions and sculptures testify to the immense significance of this Roman settlement as a health resort during the said period.
Apart from the original stone sculpture (statues and reliefs) and epigraphic monuments (altars and votive inscriptions), architectural elements and other, smaller archaeological artefacts the exhibition also features replicas of statues and reliefs from the earlier excavations (the originals form part of the permanent collection of the Varaždinske Toplice Regional Museum), 3D-reconstructions, photos and videos. The exhibition is the first public showing of most of the featured exhibits, coming to Ljubljana directly from the Austrian restoration workshops.
