For archaeologists the discovery of the port of Herakleion-Thonis in Aboukir has been a triumph. Excavations have revealed a huge amount of treasure including giant 5m-high statues (raised from the site), remnants of temple buildings, gold coins and jewellery. For the non-archaeologist diver though, the major sight in this area is the L'Orient wreck (Napoleon's flagship that sank in 1798). Depth: 14m; rating: intermediate. Dive can be arranged through Alexandra Dive.
