The Palace of Culture and Science is Warsaws tallest building at 237 meters (including spire) and one of Europes tallest buildings. Built in 1952-1955 as a gift from the Soviet Union, this Stalinist architecture landmark contains theaters, cinemas, museums, offices, and a congress hall. Despite its controversial history as a symbol of Soviet domination, it remains Warsaws most recognizable building with a popular observation deck on the 30th floor.
