Location: Berlin is located in the northeastern corner of Germany on the banks of the river Spree
Area: 883 sq km (340 sq mi) 
Population : 3,438million people as of 2008
Economy: 
 Berlin's economy is based around their three main
industries: communications, life sciences, and transportation. Berlin's
technology sector is extremely fast growing as new modern technologies are
being brought in. Being the second largest city in Germany tourism has always
been big and it is becoming increasingly important to Berlin's economy. The
entertainment and clubs alone attract over ten thousand tourists. Even though
Berlin is one of the most modern states in Germany and one of the most popular
tourist destinations, it has the most people living off of welfare; and has
accumulated more debt than any other city in Germany.
History
  Berlin joined the Republic in 1990 after west and
East Berlin were united again. 
Before 1871 Berlin was one of the many German
states that were scattered through the center of Europe.
  It was one of the most active and economic
states in “Germany” thanks to the industrial revolution. Before 
1918 Berlin was
as it is now the capital of Germany.
 
During the first world war the citizens of Berlin often suffered from a
lack of food due to military operations .
 
 Before that in 1914 the famous
Reichstag was constructed and used as the parliament building. Before 1948 it
was the capital of Nazi Germany and was heavily damaged by bombing and building
to building combat. There was a high unemployment rate in Berlin due to the
Great depression before the rise of the Nazi party.
  Well known sites includes 
1. 
Brandenburg Gate:
 Located on the western edge of Pariser Platz
just inside the former East Berlin is 26m (65 ft) high, 65.5 m (213 ft) wide
  and 11 m (36 ft) thick.Built according to the plans of 
Carl Gotthard Langhans from 1788 to 
1791,  the Brandenburg Gate is modelled on the Propylaeum of Athens’ 
Acropolis.   It consists of twelve Doric columns,
  six on each side creating five portals. The Quadriga, a statue
   consisting of the goddess of peace, driving a four-horse triumphal chariot
  is mounted above the gate, which 
  is flanked by two smaller buildings in similar style which served as 
  gatehouses.
When the Nazis ascended to power they used the 
Gate as a party 
symbol. The Gate survived World War II and was one of the damaged 
structures still standing in the Pariser Platz ruins in 1945.The 
gate was badly damaged with holes in the columns from bullets
 and nearby explosions. Following Germany's surrender and the 
end of the war, the governments of East Berlin and West Berlin 
restored it in a joint effort. The holes were patched, and were 
visible for many years following the war.
During 1990, the 
Quadriga was removed from the gate as part of renovation work 
carried out by the East German authorities following the fall of 
the wall in November 1989. Germany was officially reunified in 
October 1990.
On December 21, 2000, the Brandenburg Gate was privately refurbished at a cost of six million Euros.
On
 October 3, 2002, the twelfth anniversary of German Reunification,
 the Brandenburg Gate was once again reopened following 
extensive refurbishment.
The Brandenburg Gate is now again closed for vehicle traffic.

The Reichstag
Designed by
 Paul Wallot is
 situated at the northern end of the Ebertstrasse and near the south 
bank of the Spree River not far from the Brandenburg gate is Germany's 
parliament building.In 1918 the first German republic was declared from 
its balcony.In 1933 it was set on 
fire ostensibly
 by enemies of the newly installed Nazi government who used 
this as a convenient excuse to tighten their grip on power. During the 
second war it was damaged by allied bombing and was one of the last 
building in Berlin to fall to the soviet army in 1945. it was damaged 
during the second war by allied bombing and was one of the last building
 in Berlin to fall to the soviet army in 1945. 
During the 
reconstruction, the building was first almost completely 
gutted, taking out everything except the outer walls, including all 
changes made by Baumgarten in the 1960s. Respect for the historic 
aspects of the building was one of the conditions stipulated to the 
architects, so traces of historical events were to be retained in a 
visible state. Among them were graffiti left by Soviet soldiers after 
the final battle for Berlin in April–May 1945. Written in Cyrillic 
script, they include such slogans as “Hitler kaputt” and names of 
individual soldiers. However, graffiti with racist or sexist themes were
 removed, in agreement with Russian diplomats at the time.The large 
glass dome at the very top of the Reichstag has a 360-degree 
view of the surrounding Berlin cityscape. The main hall of the 
parliament below can also be seen from inside the dome, and natural 
light from above radiates down to the parliament floor. A large sun 
shield tracks the movement of the sun electronically and blocks direct 
sunlight which would not only cause large solar gain, but dazzle those 
below. Construction work was finished in 1999 and the seat of parliament
 was transferred to the Bundestag in April of that year. The dome is no 
longer open to visitors without prior registration.
The reconstruction was completed in 1999, with the Bundestag 
convening there officially for the first time on 19 April of that year. The Reichstag is now 
the second most visited attraction in Germany,
 not least because of the huge glass dome that was erected on the roof 
as a gesture to the original 1894 cupola, giving an impressive view over
 the city, especially at night.
3. 
Potsdamer Platz 
Once
 the busiest crossing in Europe, The Potsdamer Platz was completely 
destroyed after the war. In 1988 the new Potsdamer Platz, full of modern
 buildings, officially opened. It is named after the city of 
Potsdam,
 some 25 km to the south west, and marks the point where the old road 
from Potsdam passed through the city wall of Berlin at the Potsdam Gate.
The large new underground station, 
                          shopping arcade and entertainment center have brought 
                          new life to the Potsdamer Platz.
                          It still is more of 
                a tourist attraction than a 'natural' square, but with the construction of 
                more residential buildings in the neighborhood, the 
                area has started to grow back to its former status: 
one of the liveliest squares in the country.
4. 
Holocaust Memorial 
Designed by U.S. architect 
Peter Eisenman's
 to commemorate the murder of six million Jews at the hands of Hitler 
and his forces  Occupies about 205,000 square feet (19,000 square 
meters) of space near the 
Brandenburg Gate
 and just a short distance from where the ruins of Hitler's bunker is 
buried, the Berlin Holocaust Memorial is made up of 2,711 gray stone 
slabs that bear no markings, such as names or dates.
The slabs undulate in a wave-like pattern. Each is a five-sided 
monolith, individually unique in shape and size. Some are only ankle 
high while others tower over visitors.  The paths that are shaped 
between the slabs undulate as well. Visitors may walk through the memorial in any direction as there is no 
set pattern to the stones.  The architect has said that he hopes it will
 merely become a natural part of the city, blending in with its 
background; used for shortcuts on the way home from work or a place of peace and quiet on a chaotic day. 
5. 
Berlin Wall
The Berlin Wall was a massive cement wall built after World War II 
(August 1961) which separated the city in an eastern and western 
part, was the symbol of the Cold War. Built by the government of the DDR 
to prevent East Germans from escaping to the West,This spread families and friends apart. The tense situation 
lasted long, most of the Berlin 
Wall has been demolished since the border between East and West Berlin 
opened finally in November 1989, the wall, and its entire 
symbolic halo, was taken down.
Famous people from Berlin 
1. 
Georg Simmel
Simmel was a representative of the first generation of German 
sociologists. Even today he remains famous as the author of 'The 
Philosophy of Money', 'The Metropolis and Mental Life' and 'The 
Stranger'. Although born in Berlin to a large Jewish family, he was 
raised,a Catholic. He studied philosophy and history at the Humboldt 
University of Berlin, where he received a title and the position of 
'privatdozent in 1885'. His lectures on philosophy, ethics, psychology 
and sociology attracted Berlin's intellectual elite. In 1903, along with
 Max Weber, Ferdinand Tönnies and Rudolf Goldscheid, he founded the 
German Society for Sociology. His works served as the core of the  
future theory of symbolic interactionism, in that he claimed that a 
society is a web of multiple human relations between individuals who are
 in constant interaction with each other. In 1890, Simmel married Gertud
 Kinel, who, writing  under the pseudonym of Marie-Luise Enckendorf,  
was a philosopher herself, and the couple had a son. It wasn't until 
1914 that he received a full professorship from the University of 
Strasbourg. Simmel was the author of hundreds of articles and about 
twenty books.He died from cancer in September of 1918, shortly before 
the end of World War I., according to 
Europe Cities.
