River port, navalia and harbour temple at Ostia: new results of a DAI-AAR Project

Since 1996 the German Archaeological Institute and the American Academy in Rome have been conducting a joint urbanism project on the unexcavated parts of Rome's port city. The combined use of geophysical surveys of large areas, systematic analysis of aerial photographs, and selected stratigraphic sondages has not only complemented the previously known plan of the city but also brought much new information on the urbanistic development of previously unknown sectors. One of the most important results of the 2000 and 2001 seasons is the proof that a harbor basin existed just inside the ancient mouth of the Tiber. On the E side of that basin we investigated an unusual structure: a large terraced construction the vaulted substructure of which seems to have served in part as shipsheds and in part as storage and commercial space, and, above, a marble temple, oriented toward the mouth of the Tiber and surrounded by porticos.
