The Strait of Messina is a narrow strait between the eastern tip of Sicily and the western tip of Calabria in Southern Italy. It connects the Tyrrhenian Sea to the north with the Ionian Sea to the south, within the central Mediterranean. At its narrowest point, between Torre Faro and Villa San Giovanni, it is 3.1 km wide. At the city of Messina it is 5.1 km wide. The strait's maximum depth is about 250 m.
The strait has strong tidal currents that create a unique marine ecosystem. A natural whirlpool in the northern portion of the strait has been linked to the Greek legend of Scylla and Charybdis. In some circumstances, the mirage of Fata Morgana can be observed when looking at Sicily from Calabria. With its bottleneck shape, it is also a compulsory point of transit in the migration of many bird species.
In 1957, a 220 kV overhead power line was built across the Strait of Messina. Its pylons are among the highest in the world. This power line has since been replaced by a submarine power cable, but the pylons remain and are protected as historical monuments.
