Quay premiered in Manhattan.
In old ports such as London (which once had around 1700 wharves) many old wharves have been converted to residential or office use
 Commercial ports may have warehouses that serve as interim storage: where it is sufficient a single wharf with a single berth constructed along the land adjacent to the water is normally used; where there is a need for more capacity multiple wharves, or perhaps a single large wharf with multiple berths, will instead be constructed, sometimes projecting over the water
