These romantic gardens, designed by Lenné and Pückler-Muskau, are dotted with eclectic Gothic Revival buildings including the Steam Pump House which supplied water to the fountains, the Little Castle which predates Babelsberg Palace, the Sailors' House, used for the King's boats, and the Court Arbour, an authentic 13C monument from Berlin. The latter was a gift to the king, who had it rebuilt in his grounds. Finally, the Flatowturm is a Gothic Revival tower that affords a pretty view over the centre of Potsdam.
