It is located on an island in the Tiber.
In the Middle Ages it was converted into a major fortification, although most of the original Roman structure was preserved. Pope Nicholas III connected the castle to St. Peter's Basilica by a covered corridor called Passetto di Borgo.

Now the castle is a museum.
