With 500 ha of parks and 150 buildings constructed
between 1730 and 1916, Potsdam's complex of palaces and parks forms an
artistic whole, whose eclectic nature reinforces its sense of
uniqueness. It extends into the district of Berlin-Zehlendorf, with the
palaces and parks lining the banks of the River Havel and Lake
Glienicke. Voltaire stayed at the Sans-Souci Palace, built under
Frederick II between 1745 and 1747.
