More than 30 palaces and gardens in Berlin and Brandenburg invite visitors to go on lively time travels back into the brilliant era of the Prussian kings and queens. Testimonies to the accomplished architecture and landscape gardening in Prussia, they have largely belonged to the UNESCO World Heritage since 1991. Their paradisiacal beauty is in keeping with their sobriquet “Prussian Arcadia.” Among these are the world renowned Sanssouci Palace in Potsdam and Charlottenburg Palace in Berlin.

Le palais de plaisance de Frédéric le Grand présente une magnifique architecture de style rococo et un magnifique jardin. Le 14 avril 1745, la première pierre du célèbre palais de Sanssouci fut posée. Sanssouci est un chef-d'œuvre d'architecture, de sculptures et d'art des jardins.

Un palais colossal, dont la haute coupole à tambour est reconnaissable de loin, s'élève à l'extrémité ouest de la Hauptallee (la promenade principale) du parc de Sanssouci : le Neues Palais (Nouveau Palais). Contrairement au palais de Sanssouci, intime et plutôt modeste, ce vaste complexe répondait à des besoins officiels et représentatifs. De grandes salles de banquet, de splendides galeries et des suites majestueuses, sans oublier le théâtre baroque de Sanssouci dans l'aile sud, attendent les visiteurs à l'intérieur. Une sélection d'œuvres d'art et d'arts décoratifs du XVIIIe siècle peut être admirée dans son contexte d'origine. Le Nouveau Palais est la dernière résidence royale que Frédéric le Grand aurait construite dans son parc. Il témoignait de la puissance et de la richesse intactes de l'État prussien après les privations de la guerre de Sept Ans (1756-1763).

The Dutch Quarter, colloquially also known as the Dutch Quarter, is a district in the center of Potsdam that was built between 1733 and 1742 as part of the second city expansion under the direction of the Dutch master builder Jan Bouman from Amsterdam.[1] The quarter consists of 134 brick houses, which are divided into four squares by Mittelstrasse and Benkertstrasse. Under Friedrich Wilhelm I, known as the "soldier king", the district was planned and the two western squares were built. After his death in 1740, his son and successor Frederick II had the quarter with the two eastern squares completed largely according to his father's plans.

Cecilienhof Country House, built from 1913–17 according to plans by Paul Schultze in the style of a country manor, was the last palace erected by the Hohenzollerns. From July 17 to August 2, 1945, the summit meeting of World War II’s victorious powers took place here, attended by the “Big Three” – the American president Harry S. Truman, the British prime minister Winston Churchill (followed by his successor Clement Attlee), and the Soviet head of state Joseph Stalin. The Potsdam Conference was one the most important historical events of the 20th century. It is seen around the world as a symbol of the end of World War II and the beginning of the Cold War, which led to the division of Europe and the erection of the Berlin Wall. The Potsdam Agreement adopted at Cecilienhof laid the groundwork for a new order in Germany, Europe, and the world after World War II.
