In 1784, from the initiative of king Stanisław August Poniatowski, alongside Nowowiejska Street, the settlement of Nowa Wieś (lit. from Polish: New Village) was built, where the inhabitants of the village of Ujazdów, who were displaced due to construction of Ujazdów Castle there, were settled. It consisted of twelve houses, placed symmetrically on both sides of the street, located between Saviour Square and Polytechnic Square.[3]
In 1822, next to the square, between Marszałkowska and Mokotowska Streets, the Piskorowski Farm, a 5-hectare farm, with an orchard and a greenhouse vineyard, was founded.[1][4] In 1829, on a part of the farmland, the Red Tavern (Polish: Czerowna Karczma), owned by the Garnier family, and made from red brick, was constructed.[4][5]
After 1880, tenements were constructed around the square.[5] Around 1881, the square was connected with the horsecar line, which was replaced in 1908 with an electric tram line.[6] Until 1968, the tramtracks ran alongside the roundabout, circulating the square, but since then, they go through its middle.[5][7]
During the Second World War, while the city was under the German occupation, the Ringstand small bunker made from reinforced concrete was placed at the square. It was one of 60 bunkers of its type, installed across the city, as part of the fortification project known as Festung Warschau. The bunker was part of the fortification lines stretching between Narutowicz Square and the Vistula river. It was discovered in 2011 during the renovation works.[9][10] It was originally planned to remove and relocate it to the Polish Army Museum, however, it was ultimately decided to leave it in its current location.[11]
In 1944, during the Warsaw Uprising, the square and its surrounding area was a site of battle, which among others, included the Ruczaj Battalion of the Home Army.[12] It was controlled by the German forces, from the bunker in the nearby building of the former Ministry of War.[13] After the fall of the uprising, the buildings around the square were destroyed by the German forces. This included the Church of the Holiest Saviour, in which a bomb was detonated. It was fully reconstructed in 1955.[14]
Between 1950 and 1952, around the southern portion of the square, socialist realistic multifamily buildings, with a colonnade and stores behind the arcade, were constructed.[15] The three best-preserved tenements were also reconstructed.[16] The area became part of a then-developed housing estate of the Marshal Residential District.[15]
On 8 July 2012, at the square, the Rainbow art installation, made by Julita Wójcik, which consisted of a metal arch, covered in thousands of plastic colourful flowers, was unveiled.[17] It became associated with the LGBT rights movement due its resemblance to its symbol, the rainbow flag. Said association, and its location near the Church if the Holiest Saviour, caused numerous controversies and protests by conservative groups, with many calls for its removal.[18] The sculpture was set on fire during the night from 12 to 13 October 2012 by an arsonist.[19] Between 2012 and 2014, the installation was set on fire by arsonists four more times, including by a large group of far-right rioters during the celebrations of the National Independence Day of Poland on 11 November 2013. It was rebuilt each time.[20][21] It was eventually permanently removed by the city on 27 August 2015.[17]
In recent years, the square has become a meeting place for students, artists, and hipsters.[22]
