In 1916, while preparing construction of a new port, French engineer Gaston Jondet found a sophisticated ancient port facility west of Pharos. Kamal Abu el-Saadat continued research in the 1960s with a pioneering submarine archaeology campaign which found more ruins and a 25-ton statue fragment. Another campaign began in the 1990s under the supervision of Franck Goddio, finding numerous artifacts including twelve sphinxes, some apparently removed from Heliopolis by the Ptolemies.[13]
