The area around the Bay of Gibraltar has been inhabited for millennia and the bay itself has been used by merchant shipping for at least 3,000 years. The Phoenicians are believed to have had a settlement near Gibraltar and the Romans established the town of "Portus Alba" ("White Port") on the site of modern Algeciras. Later peoples, notably the Moors and the Spanish, also established settlements on the shoreline during the Middle Ages and early modern period, including the heavily fortified and highly strategic port at Gibraltar, which fell to England in 1704.
