The Viktoriapark is an urban park in the district of Kreuzberg in Berlin, Germany. The major landmark of the park is a cast iron monument dedicated by King Frederick William III of Prussia to the "liberation battles" (Befreiungskriege) of the War of the Sixth Coalition fought at the end of the Napoleonic Wars. A re-design of the Viktoriapark in 1888 by then city parks director Hermann Mächtig resulted in the current mountainesque character including the construction of the 24 m (79 ft) waterfall.

The Brandenburg Gate is one of Berlin’s most important monuments – a landmark and symbol all in one with over two hundred years of history. A former symbol of the divided city, it drew visitors who used to climb an observation platform in order to get a glimpse of the world behind the Iron Curtain, on the other side of the barren “death-strip” which separated east from west Berlin, geographically and politically. When Germany was reunified following the fall of the Berlin in November 1989 the Brandenburg Gate quickly reinvented itself into the New Berlin’s symbol of unity. It was officially opened to traffic on December 22, 1989.

Sanssouci is the name of the former summer palace of Frederick the Great, King of Prussia, in Potsdam, near Berlin. The palace's name emphasises this; it is a French phrase (sans souci), which translates as "without concerns", meaning "without worries" or "carefree", symbolising that the palace was a place for relaxation rather than a seat of power. Sanssouci and its extensive gardens became a World Heritage Site in 1990 under the protection of UNESCO in 1995..
