A 
harbor (or 
harbour in international usage) is a place where ships may shelter. Often it is used as a synonym for 
port: a 
coastal[?] or riverine facility where 
ships can load and unload. The port will typically consist of a 
water space enclosed by wave breakers, a number of quays or 
piers[?] where the ships may be moored, magazine buildings for storage of goods and a 
transport system for relaying goods inland. Typically 
railway and 
road transport will be utilized. Additional possibilities are 
pipeline transport and further 
ship transport with smaller ships.
During the D-Day operations of 1944, two artificial harbors (codenamed Mulberry[?]) were built just off the invasion beaches.
