Hajja is a settlement located in the western coastal region of Morocco, near Rabat. [1] The earliest recorded history of the general vicinity is associated with the now-ruined medieval archeological site Chellah, situated along the estuarine portion of the Oued Bou Regreg. Chellah was originally settled by the Phoenicians, and later became a Roman settlement, [2] before it was abandoned in Late Antiquity. [3]
