A wharf is a structure built along the shore of a body of water, like a river or ocean, where ships can dock to load and unload cargo. It usually consists of a platform supported by piles or pillars, allowing boats to come close to land. Wharves are essential for trade and transportation, as they provide a safe place for vessels to access goods and passengers. In addition to cargo, wharves can also be used for recreational purposes, such as fishing or sightseeing. Many cities have developed their waterfronts with wharves to attract tourists and enhance local economies.
