Discovery of a hypocavity in the Insulla XLVI area

In this paper we present the XLVI insula in its youngest phase of use, from the beginning of the 4th century onwards. In two rooms of the insula, located within our excavation field, we discovered the remains of a hypocaust, a floor heating system. The better-preserved hypocaust was originally built of brick columns on which brick slabs were laid to form a mortar screed with a mosaic of small stone cubes. As the hypocaust had settled or been damaged in one of the corners during the use of the space, the corner was rehabilitated. The rehabilitation was carried out using Moravian sandstone pillars and slabs, and a mortar screed with brick cubes was used as a pavement.
