Several medieval written sources mention a synagogue within Diocletian’s Palace. The most important document of these references is a list of the possessions of the archbishopric of Split in 1397. A synagogue is mentioned in the context of the archiepiscopal palace. The location of the synagogue is described alongside the vaulted space underneath the house of ‘the late Radovan’, in the eastern substructures of Diocletian’s Palace. Here, the synagogue and the oldest Jewish neighborhood would have been in constant use from Antiquity to the Middle Ages. In a great fire of 1506, the archbishop’s palace was burned down, the synagogue with it, after which this part of the city lay long in ruins.
