The investigation of the newly discovered Large Thermal Building was part of the excavations of the central urban core of the Roman city Scupi between 2008 and 2011. The therma is located in a quarter which is limited by two parallel streets, on the north and south side, and by the cardo street on the west side. According to the disposition of the uncovered rooms and the analysis of the investigated part of the new bath, it seems that the building occupies the whole city quarter. The research to this moment has shown the typical, adjacent arrangement of the rooms in a Roman bath. The thermal rooms are located in the south part of the building in accordance with the Roman architectural propositions where the caldarium and tepidarium are oriented toward the sunny southwest side. The investigation shows that the building was constructed in the 2nd century. The building existed for a long period of time during which there were several changes in the plan. An Early Christian basilica with an atrium was built on top of the south part of the bath at the beginning of the 6th century, and the rest of the building was covered by dwellings of the so-called micro-housing complex of Scupi, documented at several locations in the city.

The number of rooms, their disposition, the size of the whole thermal complex, the masonry, the rich decoration of the walls with frescoes, graffiti and mosaics with golden foil, the gorgeous statue of Venus Pudica, the two stone monuments with Latin inscriptions, one of which is a votive altar dedicated to the goddess Venus, and the other is a specific monument with a capital where the city aedile is mentioned in the inscription, and the numerous objects made of clay, metal, glass, bone and numerous numismatic material, suggest that this therma was an elaborate large building.
