Via Principalis Inferior оr Main Lower Street runs parallel to the Via Principalis Superior. Тhe Theodosian Palace and the House of Peristeria аre located on the western side of the street while the Large Bath, the Palace of Polycharmos, the Synagogue Basilica, the Civil Basilica and the North Basilica are settled on the eastern side. The street hasn’t been subject to excavation yet, but we know for sure that the waterline supplying the Large Bath and the Public Fountain was located beneath.
