Tyre (ˈtaɪər; صُور; 𐤑𐤓, Týros) is a city in Lebanon, one of the oldest continually inhabited cities in the world, though in medieval times for some centuries by just a tiny population. It was one of the earliest Phoenician metropolises and the legendary birthplace of Europa, her brothers Cadmus and Phoenix, as well as Carthage's founder Dido (Elissa). The city has many ancient sites, including the Tyre Hippodrome, and was added as a whole to UNESCO's list of World Heritage Sites in 1984. The historian Ernest Renan noted that "One can call Tyre a city of ruins, built out of ruins".
Today Tyre is the fourth largest city in Lebanon after Beirut, Tripoli, and Sidon. It is the capital of the Tyre District in the South Governorate. There were approximately 200,000 inhabitants in the Tyre urban area in 2016, including many refugees, as the city hosts three of the twelve Palestinian refugee camps in Lebanon: Burj El Shimali, El Buss, and Rashidieh.
Tyre juts out from the coast of the Mediterranean Sea and is located about south of Beirut.
It originally consisted of two distinct urban centres: Tyre itself, which was on an island just offshore, and the associated settlement of Ushu on the adjacent mainland, later called Palaetyrus, meaning "Old Tyre" in Ancient Greek.
Throughout history from prehistoric times onwards, all settlements in the Tyre area profited from the abundance of fresh water supplies, especially from the nearby springs of Rashidieh and Ras Al Ain in the South. In addition there are the springs of Al Bagbog and Ain Ebreen in the North as well as the Litani River, also known as Alqasymieh. The present city of Tyre covers a large part of the original island and has expanded onto and covers most of the causeway built by Alexander the Great in 332 BC. This isthmus increased greatly in width over the centuries because of extensive silt depositions on either side. The part of the original island not covered by the modern city of Tyre is mostly of an archaeological site showcasing remains of the city from ancient times.
