Brandenburg
Brandenburg is a German federal state encircling Berlin. State capital Potsdam is known for lavish Sanssouci Palace, summer home of Frederick the Great. Nearby, the Renaissance-style Orangery Palace has formal gardens, and the 19th-century Roman Baths blend several architectural styles. The Tudor Revival Cecilienhof hosted a famous WWII summit. Southeast of the city is Spreewald, a huge forest with rivers and lakes.
