Tiber Island

The Tiber Island (Italian: Isola Tiberina, Latin: Insula Tiberina) is the only river island in the part of the Tiber which runs through Rome. Tiber Island is located in the southern bend of the Tiber.

The island is boat-shaped, approximately 270 metres (890 feet) long and 67 metres (220 feet) wide, and has been connected with bridges to both sides of the river since antiquity. Being a seat of the ancient temple of Asclepius and later a hospital, the island is associated with medicine and healing. The Fatebenefratelli Hospital founded in the 16th century, and the basilica church of San Bartolomeo all'Isola dating from the 10th century, are located on the island.

The island has been linked to the rest of Rome by two bridges since antiquity, and was once called Insula Inter-Duos-Pontes which means "the island between the two bridges". The Ponte Fabricio, the only original bridge in Rome, connects the island from the northeast to the Field of Mars in the rione Sant'Angelo (left bank). The Ponte Cestio, of which only some original parts survived, connects the island to Trastevere on the south (right bank).

There is a legend which says that after the fall of the hated tyrant Tarquinius Superbus (510 BC), the angry Romans threw his body into the Tiber. His body then settled onto the bottom where dirt and silt accumulated around it and eventually formed Tiber Island. Another version of the legend says that the people gathered up the wheat and grain of their despised ruler and threw it into the Tiber, where it eventually became the foundation of the island.

Prior to the 3rd century BC, Roman use of the island is not mentioned by any sources.

Tiber Island was once the location of an ancient temple to Aesculapius, the Greek god of medicine and healing. In 293 BC, there was a great plague in Rome. Upon consulting the Sibyl, the Roman Senate was instructed to build a temple to Aesculapius, the Greek god of healing, and sent a delegation to Epidauros to obtain a statue of the deity. The delegation went on board a ship to sail out and obtain a statue.

Following their belief system, they obtained a snake, closely associated and dear to the god, from a temple and put it on board their ship. It immediately curled itself around the ship's mast and this was deemed as a good sign by them. Upon their return up the Tiber river, the snake slithered off the ship and swam onto the island. Believing this was an incarnation of the god himself, a temple to Aesculapius was erected just where the serpent landed.

The island may have been chosen as the site for the temple to distance it from the rest of the city, as well as for access to flowing water for use in the temple.
