Google Earth

If you open the file ostia.kmz by clicking on it, you will fly to a satellite photograph of Ostia and Portus in Google Earth, with several placemarks. Google Earth should of course be installed on your PC.

Virtual Earth

Also try Microsoft's Virtual Earth, especially the bird's eye view. Ostia is here.

The ruins of Ostia Antica. Photograph placed on the web by Paolo Fusco.
