A powerful earthquake in 1202 devastated a broad stretch of the Levantine coast and adjacent inland cities. Numerous medieval writers in Latin, Arabic, Syriac, and Old French describe the destruction, and although they wrote in different places and contexts, their accounts collectively indicate a single regional disaster affecting much of the eastern Mediterranean littoral. Only one known source, however, mentions damage to Beirut. The Chronicle of Ernoul and of Bernard le Tresorier reports that earthquakes brought down the walls of Tyre, Beirut, and Acre, while noting that many of these structures were later rebuilt.
