Monumenti repubblicani di Ostia antica

This article examines the chronological relationship between some Republican buildings of Ostia Antica and the so-called Mura Sillane. The author studies the so-called Monumento Repubblicano and its architectural function and the sanctuary of the Quattro Tempietti, the phases of their construction and the stratigraphy of the large square in front of the temples. To suggest the chronology of these buildings, the author using D. Vaglieri's excavation notes and comparing them with the results of new archaeological research, reconstructs the stratigraphic sequence of the Decumanus Maximus between the archaic walls of the castrum and the Porta Romana.
