The Marmorpalais is a former royal residence in Potsdam, near Berlin in Germany, built on the grounds of the extensive Neuer Garten on the shores of the Heiliger See. The palace was commissioned by King Frederick William II of Prussia and designed in the early Neoclassical style by the architects Carl von Gontard and Carl Gotthard Langhans. Despite the name, brick is the main material. The palace remained in use by the Hohenzollern family until the early 20th century. It served as a military museum under communist rule, but has since been restored and is once again open to the public.

Neuer Garten
Stroll around New Garden (part of the UNESCO world heritage ensemble), on the banks of the river Havel. Spanning an area of 102 hectares, this park was created in 1787 by Friedrich Wilhelm II in contrast to the Baroque Park Sanssouci. It borders with two lakes, and hosts the Marble Palace and the Palace Cecilienhof. It was here that Attlee, Stalin and Truman met for the Potsdam Conference, at the end of World War II.
Gedenk- und Begegnungsstätte Ehemaliges KGB-Gefängnis Potsdam
Memorial and meeting place at the former KGB prison. From August 1945 it was occupied by Soviet forces. It was reconstructed as a prison for counterintelligence. Today it's been left standing to remind people of the depressing reality of dictatorships.
Schloss Cecilienhof
Alexandrowka consists of a few "Russian Style" houses built for Russian immigrants during the reign of "The Soldier King". House No. 2 (Haus 2) has a very interesting museum while House No. 4 (Haus 4) has an excellent café.
Right in the middle of Potsdam are the "Dutch Quarters", built in the 18th century by Dutch master builder Johann Boumann to attract other Dutch artisans. The quarters consist of 134 red-brick houses, divided into four blocks. The history of the Dutch Quarters can be seen in the Jan Bouman house in Mittelstraße 8.
