The Brandenburg Gate (German: Brandenburger Tor), originally called the Gate of the World, 
is a triumphal arch, a symbol of Berlin and Germany. Architectural monument
It was built in the period 1789 - 1791, commissioned by King Friedrich Wilhelm II and made according to the conceptual design of Karl Langhans in the style of classicism. The propylaea of the Athenian Acropolis of Ancient Greece served as a prototype for the construction of the Brandenburg Gate. The Brandenburg Gate 
is the only one preserved from the so-called city gates of the German capital. 
Decorative elements Its facade decoration and arrangement are the work of Johan Shadov, who also designed the 6-meter-high quadriga, ruled by the Roman goddess of victory Victoria in the form of a triumphal crown. After Napoleon Bonaparte's victory over Prussia in the so-called Napoleonic Wars, the French emperor ordered the triumphal crown to be dismantled and transferred to Paris. After the Battle of Leipzig and Napoleon's forced dethronement with exile to the island of Elba following his loss at the Battle of Waterloo, the triumphal crown was returned in 1814 back to Berlin, receiving an Iron Cross under the Roman eagle by Karl Schinkel in place of the olive branch in Victoria's hand. On August 13, 1961, the passage through the door from east to west and back was blocked by the Berlin Wall. On November 9, 1989, under the pressure of the political wind of change (exactly 200 years after the beginning of the construction of the gate), the wall symbolizing the Iron Curtain and marking the beginning of the end of the Cold War fell, after which the passage through the gate of the world was free again.Germany was reunified, thus symbolically restoring its dignity after its loss in World War II, along with that of the German nation among the free nations of the world. After the fall of the Berlin Wall, the Red Army left East Germany.

The Reichstag building in Berlin was created to house the German Reichstag - the original parliament of the German Empire.
It was opened in 1894 and performed its functions until 1933. It again became the seat 
of the German Parliament in 1999 after a reconstruction led by the world-famous architect 
Norman Foster. Today's German parliament is called the Bundestag. The Reichstag as an institution dates back to the time of the Holy Roman Empire and ceased to function as a true parliament during the German Empire (1933-1945), when the Reichstag met in the Kroll Opera House. Nowadays, the name "Reichstag" refers to the building and "Bundestag" to the institution.The dome and roof terrace of the Reichstag building can be viewed for free. The dome allows natural sunlight inside the building.

It is multifunctional, it is connected to the other museums and plays the role of an entrance to the complex.

Checkpoint Charlie (or Checkpoint C) is the most famous checkpoint on the Berlin Wall between East and West Berlin during the Cold War. 
It is named after the Western Bloc.
East German politician Walter Ulbricht made numerous efforts to obtain permission from the Soviet Union to build the Berlin Wall in 1961 and stop mass emigration to West Berlin. Checkpoint Charlie became a symbol of the Cold War, representing the East-West divide. Soviet and American tanks briefly came face to face at this checkpoint during the Berlin Crisis of 1961. On June 26, 1963, US President John F. Kennedy visited Checkpoint Charlie and observed East Berlin from a platform.
After the collapse of the Eastern Bloc and the reunification of Germany, the Checkpoint Charlie building was turned into a tourist attraction.[2] Nowadays it is housed in the Allied Museum in Berlin's Dahlem district.
Checkpoint Charlie features in numerous espionage and political Cold War novels and films.

At 368 meters, the Berlin television tower is the tallest building in Germany and the fifth tallest television tower in Europe. When it was completed in 1969, it was the second highest television tower in the world and, with over a million visitors a year,

In the opening scenes of films related to Berlin, the capital is often symbolized by the television tower, in addition to buildings such as the Brandenburg Gate, 
the Victory Column and the Reichstag building.
The building, known internally as "Telecommunications Tower 32", serves not only as the location for several radio and television stations, but also as an observation tower

Schloss Charlottenburg (Charlottenburg Palace) is a Baroque palace in Berlin, located in Charlottenburg, a district of the Charlottenburg-Wilmersdorf borough.
The palace was built at the end of the 17th century and was greatly expanded during 
the 18th century. It includes much lavish internal decoration in Baroque and Rococo styles. 
A large formal garden surrounded by woodland was added behind the palace, 
including a belvedere, a mausoleum, a theatre and a pavilion. 
During the Second World War, the palace was badly damaged but has since been reconstructed. The palace with its gardens is a major tourist attraction.

The palace complex of San Souci is located in the city of Potsdam, near Berlin. Its French name sans souci literally means "without care" and it was the summer residence 
of Frederick the Great, former King of Prussia.
The gardens were built on an area that was previously covered by extensive forests. By order of Frederick the Great, the hill was planted with terraced vines, resulting in the gardens consisting of three wide terraces designed to maximize sunlight. The palace and gardens are reminiscent of a miniature version of Versailles with beautifully landscaped lawns, shrubs and trees, decorative statues and fountains.

Decorated in Rococo style, San Souci and its magnificent gardens became
a UNESCO World Heritage Site. Not only the exterior but also the interior is richly
decorated in a style known as 'Frederician Rococo'. The King of Prussia wanted to be surrounded by beautiful objects and works of art to fill all the rooms, according to his personal taste and love of large and luxurious materials.
Marble, beautiful wooden details and charming gold decoration fill the themed rooms.
The palace is actually part of a huge park that bears the same name.
It has various palaces and garden complexes.
The New Palace
At the western end of the park, the complex is home to the imposing and much
larger New Palace, now part of the University of Potsdam, built between 1763 and 1769 to celebrate the Prussian victory over Austria during the Seven Years' War.
Due to the fact that the palace was too ostentatious, Frederick did not use it
as a personal residence, but preferred to receive guests there.
The Orangery (Orangery Palace)
Another interesting building in the park is the so-called Orangery. It is basically a conservatory where exotic plants are grown, even in the cold winter. Interestingly, it continues to function to this day. It was completed in 1864 in the Italian Renaissance style. 
With its many historic buildings, Parc Saint-Souci is an interesting place to visit and a great way to escape Berlin for the day. It covers nearly 300 hectares of land, so visitors should allow enough time to enjoy all the beauty and sights at leisure.
