Isola Sacra

One aim of the Portus Project has been to use geophysical survey to gain a better understanding of the Isola Sacra – an artificial island lying between the Tiber, Portus, Ostia and the Tyrrhenian sea.  It was traversed by a road running between Portus and Ostia, and hosted a small settlement in the north with adjacent cemetery to its south.

The geophysical survey has revealed important new details about a major new canal between Portus and Ostia, the subdivision of the landscape for agriculture, some structures associated with the marble yards of Imperial Rome, and tombs overlooking the Tiber.
