More of a circle than a square, this star-shaped roundabout was originally part of an 18th-century urban route leading to the nearby Ujazdowski Castle and Łazienki Park. Like Plac Konstytucji, after the war it became dominated by PRL-era buildings from the 1950s, but still harbours a couple gems. The first is the conspicuous Church of the Holiest Saviour, from which the square takes its name (Saviour Square). Built in neo-Renaissance style in the 1920s, that it stands is a marvel, considering it was dynamited by the Nazis during WWII and then tagged for demolition by the communists. The other pre-war building here is the handsome Jasieńczyk-Jabłoński tenement (Mokotowska 12), erected in 1910. Upon completion, it was not only one of the most modern, but also the tallest residential building in Warsaw (38 m). From 2012–2015, Julita Wójcik's "Rainbow" art installation notably soared over Plac Zbawiciela. A 9m high 26m wide rainbow made of plastic flowers, the piece proved too controversial for PL's anti-LGBT factions, who repeatedly lit it on fire until it was removed. Though there are plans to replace it with a fireproof version, the current political climate doesn't seem conducive to its return for the moment. Despite that unpleasantness, Saviour Square today is quite the progressive meeting place for students, artists and activists who favour the hip bars and sidewalk cafes here, like Plan B (Al. Wyzwolenia 18) and Charlotte (Al. Wyzwolenia 18/2U).
