At the time of construction it was the sixth tallest European skyscraper with eighteen stories. Built using a steel framework it was the tallest building in Warsaw until the Palace of Culture and Science was constructed. The building, designed by Marcin Weinfeld, included office space on lower stories and luxurious apartments further up. The steel framework, innovative at the time, was designed by Stefan Bryła and Wenczesław Poniż. Construction started in 1931 and used up over 2 million bricks, 2 thousand tonnes of concrete and 1500 tonnes of steel. In 1936 a large antenna was constructed on the roof by professor Janusz Groszkowski, who started the first television broadcasts in Europe from that facility. The Prudential building soon became a symbol of modern Warsaw and was featured in numerous contemporary films and advertisements. : 28 August 1944, an iconic photo by Sylwester Braun which captured the moment when the building was hit by a 2-ton mortar artillery shell during the Warsaw Uprising The Prudential was heavily damaged during World War II, particularly during the Warsaw Uprising when it was hit by approximately 1,000 artillery shells, including a single hit by 2-tonne Karl-Gerätmortar shell, leaving only the steel framework. The artillery damage bent the construction sideways, but it survived the war and was featured on numerous anti-war posters. The building was rebuilt after the war as a hotel, and its style was changed from early modern to socialist realism. The author of the new design was again Marcin Weinfeld, who adapted the building to its new role as a hotel. The "Hotel Warszawa" was opened in 1954 and included 375 rooms, a large restaurant, a café and a night club. In 2002 the hotel closed and the building sold. In 2010, it was purchased by the Likus Group, which began a slow and controversial refurbishment. The façade was returned to its pre-war art deco form, while the socialist-realist interior was completely refurbished in a contemporary style. In November 2018, the building re-opened as a 142-room luxuryfive-star Hotel Warszawa.
