Rotterdam - Delfshaven

At Voorhaven 12 is the Dubbelde Palmboom Museum, housed in a 19th century warehouse with a fine double staircase. It contains a large collection of material on the history of Rotterdam, including archaeological finds and implements and equipment illustrating the development from the earliest crafts to the mechanized industry of modern times.

Near the Dubbelde Palmboom Museum, at Vorstraat 13-15, is the Zakkendragershuisje (Porters' House), an old tin-smelting works which is still operating. Visitors can watch objects being cast in the old molds.
