Potsdam was historically a centre of European immigration. Its religious tolerance attracted people from France, Russia, the Netherlands and Bohemia. This is still visible in the culture and architecture of the city. The most popular attraction in Potsdam is
Sanssouci Park, west of the city centre. In 1744
King Frederick the Great ordered the construction of a residence here, where he could live
sans souci ("without worries", in the French spoken at the court). The park hosts a
botanical garden (
Botanical Garden, Potsdam) and many buildings: • The
Sanssouci Palace (
Schloss Sanssouci), a relatively modest palace of the Prussian royal (and later German imperial) family • The
Orangery Palace (
Orangerieschloss), former palace for foreign royal guests • The
New Palace (
Neues Palais), built between 1763 and 1769 to celebrate the end of the
Seven Years' War, in which Prussia held off the combined attacks of
Austria and Russia. It is a much larger and grander palace than Sanssouci, having over 200 rooms and 400 statues as decoration. It served as a guest house for numerous royal visitors. Today, it houses parts of
University of Potsdam. • The
Charlottenhof Palace (
Schloss Charlottenhof), a
Neoclassical palace by
Karl Friedrich Schinkel built in 1826 • The
Roman Baths (
Römische Bäder), built by Karl Friedrich Schinkel and
Friedrich Ludwig Persius in 1829–1840. It is a complex of buildings including a tea pavilion, a Renaissance-style villa, and a Roman bathhouse (from which the whole complex takes its name). • The
Chinese Tea House (
Chinesisches Teehaus), an 18th-century pavilion built in a
Chinese style, the fashion of the time. Three gates from the original city wall remain today. The oldest is the Hunters' Gate (
Jägertor), built in 1733. The
Nauener Tor was built in 1755 and close to the historic Dutch Quarter. The ornate
Brandenburg Gate (built in 1770, not to be confused with the
Brandenburg Gate in Berlin) is situated on the Luisenplatz at the western entrance to the old town. on the
Alter Markt The
Old Market Square (
Alter Markt) is Potsdam's historical city centre. For three centuries this was the site of the
City Palace (
Stadtschloß), a royal palace built in 1662. Under
Frederick the Great, the palace became the winter residence of the Prussian kings. The palace was severely damaged by Allied bombing in 1945 and demolished in 1961 by the
Communist authorities. In 2002 the Fortuna Gate (
Fortunaportal) was rebuilt in its original historic position which was followed by a complete reconstruction of the palace as the
Brandenburg Landtag building inaugurated in 2014. Nearby the square in the Humboldtstraße block, which also was demolished after getting damaged in 1945, reconstructions of several representative residential palaces including Palazzo Pompei and Palazzo Barberini
housing an arts museum were completed in 2016–2017 alongside buildings with modernized facades to restore the historical proportions of the block. The Old Market Square is dominated today by the dome of
St. Nicholas' Church, built in 1837 in the Neoclassical style. It was the last work of Karl Friedrich Schinkel, who designed the building but did not live to see its completion. It was finished by his disciples
Friedrich August Stüler and Ludwig Persius. The eastern side of the Market Square is dominated by the Old City Hall, built in 1755 by the Dutch architect Jan Bouman (1706–1776). It has a characteristic circular tower, crowned with a gilded
Atlas bearing the world on his shoulders. North of the Old Market Square is the oval
French Church (
Französische Kirche), erected in the 1750s by Boumann for the
Huguenot community. To the south lies the
Museum Barberini, a copy of the previous building, the Barberini Palace. The museum was funded by the German billionaire
Hasso Plattner. The former
Baroque building was built by
Carl von Gontard in 1771–1772, inspired by the Renaissance palace
Palazzo Barberini in Rome. The newly built museum was scheduled to open in spring 2017. The
Garrison Church contains a
Coventry chapel, an exhibition about the history of the place and a viewing platform at a height of 57 meters. Another landmark of Potsdam is the two-street
Dutch Quarter (
Holländisches Viertel), an ensemble of buildings that is unique in Europe, with about 150 houses built of red bricks in the Dutch style. It was built between 1734 and 1742 under the direction of Jan Bouman to be used by Dutch artisans and craftsmen who had been invited to settle here by
King Frederick Wilhelm I. Today, this area is one of Potsdam's most visited quarters. North of the city centre is the
Russian colony of Alexandrowka, a small enclave of Russian architecture (including an
Orthodox chapel) built in 1825 for a group of Russian immigrants. Since 1999, the colony has been part of the
UNESCO World Heritage Site Palaces and Parks of Potsdam and Berlin. East of the Alexandrowka colony is a large park, the
New Garden (
Neuer Garten), which was laid out from 1786 in the
English style. The site contains two palaces; one of them, the
Cecilienhof, was where the
Potsdam Conference was held in July and August 1945. The
Marmorpalais (Marble Palace) was built in 1789 in Neoclassical style. Nearby is the
Biosphäre Potsdam, a tropical
botanical garden.
Babelsberg, a quarter south-east of the centre, houses the
UFA film studios (
Babelsberg Studios), and an extensive
park with some historical buildings, including the
Babelsberg Palace (Schloß Babelsberg, a
Gothic revival palace designed by Schinkel). The
Einstein Tower is located within the
Albert Einstein Science Park, which is on the top of the
Telegraphenberg within an astronomy compound. Potsdam also features a memorial centre in the former
KGB prison in Leistikowstraße. In the Volkspark to the north, there is one of the last monuments dedicated to Lenin in Germany. Potsdam joined
UNESCO's
Network of Creative Cities as a Design City on October 31, 2019, on the occasion of World Cities' Day. ==Parks==
