Helen Delich Bentley Port of Baltimore
The port was founded in 1706, preceding the founding of Baltimore. The Maryland colonial legislature made the area near Locust Point as the port of entry for the tobacco trade with England. Fells Point, the deepest point in the natural harbor, soon became the colony's main ship building center, later on becoming leader in the construction of clipper ships. After Baltimore's founding, mills were built behind the wharves. The California Gold Rush led to many orders for fast vessels; many overland pioneers also relied upon canned goods from Baltimore. After the Civil War, a coffee ship was designed here for trade with Brazil. At the end of the nineteenth century, European ship lines had terminals for immigrants. The Baltimore and Ohio Railroad made the port a major transhipment point. Currently the port has major roll-on/roll-off facilities, as well as bulk facilities, especially steel handling. Water taxis also operate in the Inner Harbour. Governor Ehrlich participated in naming the port after Helen Delich Bentley during the 300th anniversary of the port.
