The Hauptbahnof is the major railway terminal in the city of Berlin. The present structure with a glass roof replaced an older 19th century building called the Lehrter Bahnof.
The Hauptbahnof was ceremonially opened by the German Chancellor Angela Merkel in 2006. It was designed by an architecture firm based in Hamburg called Gerkan Marg and Partners. It has five levels. The first level is underground and has a series of tunnels through which trains run under the River Spree. The station hall is made with steel and glass and runs in an east to west direction. At the middle of the hall is a 160 meter long and 40 meter wide station building that runs in a north south direction. It has 70,000 square meters of floor space with retail stores and cafes. All types of shops are located here from pharmacies to florists. For this reason, it has been described as a shopping center with a railway connection.
The Haupbahnof is operated by DB Station and Service and is classified as a Category I station. There are six passenger tracks on the upper level and 8 in the lower level. About 1,800 trains travel in and out every day carrying over 350,000 passengers.

The Bundeskanzleramt or German Chancellery building contains the offices and residence of the German Chancellor. It was constructed after the unification of Germany when the seat of the Chancellor shifted to Berlin from Bonn in the erstwhile West Germany.
The Bundeskanzleramt was designed by Berlin based architects, Axel Schultes and Charlotte Frank. It was completed in 2001. The structure flanks three sides of a ceremonial courtyard. It has nine floors and is 36 meters high. It has a series of free standing columns with a curved concrete roof forming an awning at the entrance. It has plenty of windows that let natural light and air into the building to conserve electricity costs. A circular staircase at the entrance leads to conference rooms, the office of the chancellor and dining rooms where official banquets are held. The Chancellery has a postmodern style of architecture and occupies a floor area of 12,000 square meters. State guests are received in the expansive courtyard. The highlight of the courtyard is an iron sculpture called Berlin by the Spanish artist, Eduardo Chillida.
The Bundeskanzleramt is one of the largest government buildings in the world. Visitors are not allowed except on the open day in September when conducted tours around the complex are organized.

The Paul Lobe Haus is one of the parliamentary buildings in Berlin. It has the offices of 22 parliamentary committees, the PR division and the office of the visitor’s service located within its walls. It was named after the last elected parliamentary president during the Weimar Republic before the Nazis assumed power.
The Paul Lobe Haus was designed by Munich based architect, Stephan Braunfels. He also designed another building called the Marie Elisabeth Leuders Haus on the other bank of the River Spree. The two structures have similar roof edges and are connected by a double sided footbridge that runs across the river to symbolize the unification of Germany. The building became functional in the year 2001.
The Paul Lobe Haus covers an area of 61,000 square meters. It has 1700 rooms that make up 550 offices for 275 members of parliament. There are also 19 meeting rooms and the 22 parliamentary committees occupy 450 offices. The structure looks like a double comb and has eight courtyards. The imposing entrance is under a porch held by four filigree columns. At the center of the building is a glass roofed hall with transparent staircases and glass elevators. There is a restaurant located within the building serving officials staff and visitors.

The Reichstag building is a historical edifice in Berlin, Germany, constructed to house the Reichstag, parliament of the German Empire. It was opened in 1894 and housed the Reichstag until 1933, when it was severely damaged in a fire supposedly set by Dutch communist Marinus van der Lubbe. During the Nazi era members of the Reichstag continued to assemble as a group in the Kroll Opera House. After its completion in 1999, it became the meeting place of the modern German parliament, the Bundestag. The Reichstag dome is the large glass dome at the very top of the building. The dome has a 360-degree view of the surrounding Berlin cityscape. The dome is open to anyone without prior registration, although the waiting queues can be very long, especially in summertime.

The Brandenburg Gate (German: Brandenburger Tor) is a former city gate and one of the main symbols of Berlin and Germany. It is located west of the city center at the junction of Unter den Linden and Ebertstraße, immediately west of the Pariser Platz. It is the only remaining gate of a series through which one formerly entered Berlin. One block to the north stands the Reichstag building. The gate is the monumental entry to Unter den Linden, the renowned boulevard of linden trees which formerly led directly to the city palace of the Prussian monarchs. It was commissioned by King Frederick William II of Prussia as a sign of peace and built by Carl Gotthard Langhans from 1788 to 1791. The Brandenburg Gate was restored from 2000 to 2002 by the Stiftung Denkmalschutz Berlin (Berlin Monument Conservation Foundation). Today, it is considered one of Europe's most famous landmarks.

The Pariser Platz is a large square located behind the Brandenburg Gate in Berlin. It was named after the French capital city, Paris to commemorate the defeat of Napoleon and occupation of France by Prussian armed forces and other armies that formed the allied forces in 1814.
The Pariser Platz was a grand square in Berlin and many important buildings stood around it. It was laid between 1732 and 1735 and was simply called the square at first before being renamed in honor of the services of the Prussian army in the defeat of Napoleon. Notable structures that flanked the square were the French and American Embassies, the Academy of Arts and the Aldon Hotel which was once the finest in Berlin. After the Berlin bombings during World War II, only the Brandenburg Gate remained standing though damaged by bombing raids and artillery fire. In divided Germany, the square was an abandoned space that divided Berlin. Today, Parizer Platz is being restored to its former glory by the city government.
Parizer Platz is an important tourist meeting place in unified Berlin. Many walking tours start here and it is also the spot where visitors can rent bikes for touring and take horse cart rides around the city. The Brandenburg gate that flanks the square is an important monument and best known landmark of Berlin.

The DZ Bank (formerly DG Bank) building is a mixed-use: office, conference, and residential complex, located at Pariser Platz 3 in Berlin. It was designed by architect Frank Gehry and engineered by Hans Schober of Schlaich Bergermann & Partner. The construction began in 1998 and was completed in 2000. Facing the Brandenburg Gate are offices, the headquarters of Deutsche Zentral-Genossenschaftsbank. On the other side, facing Behrenstraße, are 39 residential apartments. Between the two is a large atrium, designed as a venue for conferences or performances. It is covered with a sophisticated glass-grid roof, curved in a complex form typical of Gehry's designs.

Unter den Linden ("under the linden trees") is an iconic boulevard in the central Mitte district of Berlin, the capital of Germany. It is named for its linden (lime in British English) trees that line the grassed pedestrian mall between two carriageways. Unter den Linden runs east–west from the site of the former Stadtschloss royal palace at the Lustgarten park, where the demolished Palast der Republik used to be, to Pariser Platz and Brandenburg Gate. Unter den Linden at the heart of the historic section of Berlin developed from a bridle path laid out by Elector John George of Brandenburg in the 16th century to reach his hunting grounds in the Tiergarten. Well-known statues of Alexander and Wilhelm von Humboldt in front of the university as well as of the Prussian generals Scharnhorst and Bülow also adorn the street.

The Memorial to the Murdered Jews of Europe (German: Denkmal für die ermordeten Juden Europas), also known as the Holocaust Memorial (German: Holocaust-Mahnmal), is a memorial in Berlin to the Jewish victims and other victims of the Holocaust, designed by architect Peter Eisenman and engineer Buro Happold. It consists of a 19,000 square meter site covered with 2,711 concrete slabs or "stelae", one for each page of the Talmud arranged in a grid pattern on a sloping field. According to Eisenman's project text, the stelae are designed to produce an uneasy, confusing atmosphere, and the whole sculpture aims to represent a supposedly ordered system that has lost touch with human reason. An attached underground "Place of Information" (German: Ort der Information) holds the names of all known Jewish Holocaust victims, obtained from the Israeli museum Yad Vashem. It was inaugurated on May 10, 2005, sixty years after the end of World War II, and opened to the public on May 12 of the same year.

Checkpoint Charlie was one of the three crossing points from East to West Germany after the construction of the Berlin War. It later became the one of the symbols of the cold war and is a tourist attraction because of its immortalization by American movies and spy novels.
After the completion of the building of the Berlin wall, the Americans established three crossing points, A, B and C. They were called Checkpoint Alpha, Bravo and Charlie by the NATO forces. Checkpoint Charlie became the only crossing point by 1962. It was the location where the documents of visitors and diplomats were checked by East Germans before issuing visas. It was also the venue of a standoff between America and the Soviet Union with their tanks facing each other on either side of the checkpoint when an American diplomat was refused a visa soon after the building of the wall.
Today, a replica of the original Checkpoint Charlie booth stands at the site with a, ‘You are now leaving the American Sector’, sign that once marked the border between East and West Germany. There is also a museum near the venue which is dedicated to freedom with exhibits relating to the many escape attempts over the Berlin Wall.
