A lot has changed since then. Eight of the ten largest ports in the world are now to be found in China, but Europe still has quite a few very large harbors. Data via American Association of Port Authorities. This Dutch harbor was the largest in the world, until Shanghai and Singapore grew even larger in 1986. This satellite photo gives an indication of the size of the Port of Rotterdam.
It is classed as a lake, and is the world's largest, with an area of 371,800 km2 and a maximum depth of 184 metres. The Caspian Sea is rich on oil and gas.
