The Palace of Culture and Science is the tallest building in Poland and the eighth tallest building in the European Union. It is 231 metres tall, which includes a 43-metre high spire.
The building was originally known as the Joseph Stalin Palace of Culture and Science, but in the wake of destalinization the dedication to Stalin was revoked. The building was conceived as a 'gift from the Soviet people to the Polish nation', and was completed in 1955. The structure was built in three years according to the design of the Soviet architect Lev Rudnev. Architecturally, it is a mix of Stalinist architecture, also known as Socialist Classicism, and Polish historicism inspired by American art deco skyscrapers. Currently it is the headquarters of many companies and public institutions, such as cinemas, theaters, libraries, sports clubs, universities, scientific institutions and authorities of the Polish Academy of Sciences.
The tower was constructed, using Soviet plans, almost entirely by 3500 workers from the Soviet Union, of whom 16 died in accidents during the construction.

The original building was erected during the first third of the 14th century for the Brotherhood of Blackheads, a guild for unmarried German merchants in Riga. Major works were done in the years 1580 and 1886, adding most of the ornaments.
The structure was bombed to a ruin by the Germans June 28, 1941 and the remains demolished by the Soviets in 1948. The current reconstruction was erected from 1995 to 1999. Today the House of Blackheads serves as a museum and sometimes concert hall.
