Created in the 19th century, under the Congress Kingdom, the square was designed to be an elegant area of the country's capital.
After the war, city planners reconstructed only its historic western part, changing it into a rectangle.
Bank Square's present-day landmarks include Błękitny Wieżowiec (the Blue Skyscraper), and the former seat of the Ministry of Treasury now serves as Warsaw's city hall, the seat of the President of Warsaw and the provincial office of the Mazovia province.
In 2001, a monument to Juliusz Słowacki, by Edward Wittig (actually designed in 1932), was erected on the spot previously occupied by the statue of Feliks Dzierżyński.
In front of the Błękitny Wieżowiec, there is a statue to Stefan Starzyński, the pre-World War II President of Warsaw, by Andrzej Renes.
