Tyre

As Alexander could not attack the city from the sea, he built a kilometre-long two hundred foot-wide causeway (claimed so by Diodorus) stretching out to the island on a natural land bridge no more than two meters deep.
Siege of Tyre (332 BC)
The island [Tyre] lay about a kilometre from the coast in Alexander [the Great]’s days, its high walls reaching 45.8 m (150 ft) above the sea on the eastern, landward facing, side of the island.
Tyre (Wikipedia) Tyre (/ˈtaɪər/; Arabic: صُور, romanized: Ṣūr; Phoenician: 𐤑𐤓, romanized: Ṣūr; Greek: Τύρος, translit. 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”.
