The Old Lock Pump House, whose first element was built in 1837, preserves a feature of the old canal, which relied on locks and pumps to move vessels over the low divide of the Delmarva Peninsula between Chesapeake Bay and Delaware Bay. Because there are no large rivers on the peninsula, water had to be pumped uphill to fill the upper canal and locks.

Conceived as one of the major structures on the Prussian Eastern Railway, the Old Wisla Bridge at Tczew originally consisted of six wrought iron spans. Due to Germany's invasion of Poland at the beginning World War II in 1939, only three original spans remain today. These remaining spans represent a unique technical monument of civil engineering achievements in the mid-nineteenth century.
