Baltimore's shipbuilding heritage dates back to the 18th century when the city became a vital port for trade and commerce. The strategic location along the Patapsco River allowed shipbuilders to construct vessels for both local and international markets. Notable shipyards, such as Patterson Park and Canton, played significant roles in producing ships for various purposes, including fishing, trade, and military use. During the Civil War, Baltimore's shipyards were crucial for building warships for the Union Navy. The city's shipbuilding industry continued to thrive into the 20th century, contributing to the construction of cargo ships and submarines. Today, remnants of this rich maritime history can be seen in the city's waterfront and museums.
