A wharf site is a location where ships can dock and unload cargo. The term 'wharf site' is often used interchangeably with the term 'QUAY, ' which is a four-letter word that is commonly used in crosswords. A QUAY is a structure built along the shoreline of a body of water, such as a river or harbor, to provide a place for ships to dock and unload cargo. Quays are typically made of stone, concrete, or steel and are designed to withstand the force of the waves and tides.
