Modern Tyre’s peninsula geography exists largely because of Alexander’s siege causeway accumulating centuries of sediment.
Tyre, a principal Phoenician city, sat on an island roughly half a mile from the mainland, protected by walls rising up to 45 meters. When Alexander demanded surrender during his campaign against Persia, Tyre refused. Lacking a navy strong enough at first to assault it directly, Alexander ordered construction of a massive mole stretching from shore to island. The project required quarrying stone and timber while defenders launched missiles and fire attacks. The siege lasted about seven months, during which Macedonian forces eventually assembled a fleet from allied cities. Once the walls were breached, thousands were killed or enslaved according to ancient accounts. The engineering feat permanently altered local geography; sediment accumulated around the mole, joining the island to the mainland. What began as a military improvisation reshaped the coastline for centuries.

Strategically, the fall of Tyre eliminated Persian naval access to the eastern Mediterranean. It demonstrated that fortified maritime cities were vulnerable to determined engineering. Alexander’s success sent a message to other Phoenician ports weighing resistance. Control of Tyre meant control of regional shipyards and trade channels. Infrastructure became a weapon, not just a civic asset. The causeway’s construction illustrated how military logistics could override natural defenses. Geography proved negotiable under pressure.
For Tyre’s inhabitants, the siege meant watching their natural moat vanish stone by stone. A city that trusted the sea as protection discovered that labor and persistence could nullify isolation. Families endured bombardment and food shortages while construction advanced daily. The irony lies in Phoenician mastery of maritime engineering being countered by terrestrial engineering. An island identity was transformed into a peninsula identity by force. The physical scar remains visible today. A siege decision in 332 BCE still shapes satellite images.
