Fig. 2 - S2 (06.11.2020) - At the mouth of the River Tiber, Ostia (latin for "mouth") was Rome's seaport, but due to silting the site now lies 3km from the sea.
2D view
A flood altered the course of the Tiber, shortening the loop it formed upstream from Ostia, and eroded a northern part of the site.
Fig. 3 - S1 (05.10.2019) - Lying between Ostia and Fiumicino, Isola Sacra is an artificial island created by Emperor Trajan by creating a canal that linked the Tiber to the sea.
2D view
The city was finally abandoned in the 9th century due to the repeated invasions and sackings by Arab pirates.
Fig. 4 - S2 (06.11.2020) - The antique city was rediscovered in the middle of the 20th century, unexcavated areas have still been found in 2014.
