Phoenician port of Beirut, Archaeological site between Rue Allenby and Rue Foch, Beirut, Lebanon.

The Phoenician port of Beirut is an archaeological site containing remains of an ancient harbor complex built from large sandstone blocks. The excavated structures reveal how this location served as a vital trading hub along Mediterranean maritime routes.

The harbor's western bank at site BEY039 was excavated and published by Josette Elayi and Hala Sayegh in 2000, dating it to Iron Age III and the Persian period. Two 19th-century Ottoman docks were unearthed just north at sites BEY018 and BEY019. A separate alleged port, BEY194 at Mina al-Hosn, was found in 2011 and demolished on 27 June 2012.

The site lies between Rue Allenby and Rue Foch, and the surrounding district of Mina al-Hosn takes its Arabic name, "port of the fort", from the harbour tradition here. The harbour wall was built of Ramleh sandstone blocks about 60 by 30 centimetres set in grey mortar, resting on larger 100 by 60 centimetre blocks laid without mortar, a technique matching Phoenician period D.

The excavated sector BEY039 lies between Rue Allenby and Rue Foch, about 300 metres inland from today's shoreline, because Bronze Age waterfronts sat further back before coastal siltation. The 3,000 square metres examined formed the western bank of a north-to-south harbour. The separate Plot 1398 site at Mina al-Hosn, behind Hotel Monroe, was demolished on 27 June 2012, so nothing of it remains to see.

The excavations reveal multiple construction phases using different techniques, from dry stone placement to grey mortar application. This variety in building methods documents distinct periods of activity and shows how craft practices evolved over time.
