Warsaw is the biggest Polish agglomeration and the capital of Poland. There are over one and a half billion people living in the city and many more living in the adjacent areas who work, shop, or study in Warsaw. The city is the centre of Polish commercial activity. The biggest Polish companies are located in the city. For this reason, the capital attracts many young people who want to develop their careers there. Warsaw is also a buzzing academic centre, with many higher education facilities such as Warsaw University or Warsaw University of Technology. Many people dream of studying in Warsaw as it offers excellent conditions to study and fun. Warsaw is located in the centre of Poland on the Mosovian Plain. It is located on the Vistula river, the longest Polish river, which divides the city in half. The city is one of the largest in the European Union. It consists of 11 quarters. The city was severely damaged during the World War II and a large part of historical architecture has been destroyed. Still there are many beautiful objects to be found in Warsaw, such as St. John’s Cathedral, The Baths Park, or Wilanów Palace. The most easily recognized piece of Warsaw architecture is The Palace of Culture and Science, a socialist building constructed in 1955. It remains the highest building in the city, with the height of 231 metres and 42 floors. Due to its socialist history and specific looks the palace attracts a lot of resentment among some of the Polish citizens, but still many others recognize it as a piece of history and a trademark of Warsaw. Warsaw is the only Polish city with an underground system. The inhabitants may also use other forms of mass transport: trams, buses and Urban Rapid Railway. Warsaw is the seat of the most important state institutions of Poland: the parliament and the office of the president.
