About the site
Archaeological excavations in 2024 and 2025 are being carried out in areas of the planned construction of NUC II that have not been or only partially excavated in the past. The site was first excavated by Walter Schmid in 1912, and subsequently, until the 1990s, it was the site of a series of small-scale individual excavations during the renovation of roadways and utilities. In 1990, under the direction of Ljudmila Plesničar Gec, the first archaeological investigations were carried out in preparation for the construction of the new National and University Library, which continued between 1996 and 1999. In 2008, under the direction of Dr Andrej Gaspari, the remaining remains in the accessible areas planned for the construction of the NUC II were investigated. The remaining areas, which for various reasons were not accessible in 2008, will be investigated as part of the current investigations and just prior to the construction itself.
The current archaeological excavations are taking place on the northern edge of the planned NUC II construction area and cover an area of approximately 550 m². We will investigate a small part of the chardo and parts of the insul XXVII and XLVI, which were joined together in the 4th century to form a single complex, presumably in public use.
During the first months of the archaeological excavations, a previously unexplored part of the car park was excavated in the north-west corner of the car park. We documented the foundations of the new-medieval buildings and the remains of the external layout, and beneath them the remains of the medieval use of the area, with cultivated soil in which pits and ditches of various uses had been dug. Some of the ditches are the result of the excavation of stones from the Roman walls, which were used as building material in the construction of the medieval town. The youngest Roman remains on this part of the site are represented by an 80 m² area of screed, above which we documented the ruins of a ruined hypocaust, built of slabs and sandstone pillars. In the rooms to the west, we found smaller rooms with different uses. A room with an additional wall functioned as a food preparation oven and as a heating source for a smaller room next to it, in which we found very modest remains of a hypocaust with brick pillars. In the ruin above the remains of the hypocaust, there were a large number of fragments of frescoes, as well as hollow bricks (Lat. tubules), which were used as wall cladding for space heating. A special discovery is the small pool (Lat. piscina), which is almost a metre deep in older Roman deposits. The pool has semicircular ends on two sides, is lined with hydrophobic mortar and sealed with clay. A lead pipe runs through the south side at the bottom of the pool, which was a drain. Unfortunately, the stone lining of the pool has probably not survived.
In the coming months of archaeological excavations, we will continue to investigate the older Roman deposits, and we have also started excavations in the area along Rimska 1 and 3.
