Excavations at BEY039 covered 3,000 square metres (0.30 ha) and comprised the western bank of a north to south facing harbor about 300 metres (980 ft) from the sea. It was made up of Ramleh sandstone blocks measuring about 60 centimetres (24 in) by 30 centimetres (12 in), fixed with a grey mortar. This overlaid a layer of larger blocks measuring about 100 centimetres (39 in) by 60 centimetres (24 in) that were fixed without mortar.
