Located in a lush agricultural section of southern littoral of Lebanon, Tell el-Burak has been under investigation by the American University of Beirut and the University of Tübingen since 1998.
 The excavations have revealed three occupations on the tell, the latest in the Ottoman Period, the next in the Iron Age, and the earliest in the Middle Bronze Age.
 During this earliest stage the mound was built as part of a defensive structure serving as the base for a fortress on its top.
 In the Iron Age, Tell el-Burak was home to a settlement that was prosperous and peaceful, as seen in its defenseless and fine architecture.
 There is no apparent occupation in the intervening Late Bronze Age as the site was seemingly abandoned in favor of Sarepta, four kilometers to the south.
