Sielce is a neighborhood in Mokotów district of Warsaw, Poland.
Sielce is roughly bounded on the North by Podchorążych Street, the East by Czerniakowska Street, the South by Beethhovena Street, and the West by Sobieskiego Street. Its northwest corner adjoins the Royal Baths Park, also known as Park Łazienkowski, on the southwest side, with two entrances to the park (one from Gagarina Street, and one on Podchorążych).
In 1412, Duke Janusz I gave the dean of the chapter collegiate St. John a portion of land lying in the north of Siedlce (Sielce). It became the property of the church and survived until confiscation by the Prussian government during the Third Partition of Poland in 1795.
A small-sized village (5 fiefs in 1528) together with Czerniakow and Czarnów once constituted a whole.
There was a farm and Wójtostwo (town), in the sixteenth century a clothier lived in Sielcach.
In the first half of the nineteenth century, part of the land Sielc belonged to Grand Duke Constantine Pavlovich of Russia.
In 1820 he married Joanna Grudzińska, who died shortly after her husband died in 1831. They left a will in which his Polish estates - including Sielce - were bequeathed to Nicholas I of Russia, who was also King of Poland at the time.
Sielce became a part of Warsaw in 1916. At the same time, the former "Principe" street was renamed Chelmska, "Lazienkowska - Nabielaka," Long "- Iwicka," garden "-Czerska," Shared "- MAGNUSZEWSKI (then Gagarin)," Okopowa "- Cadet.
These changes marked the start of the area's transformation from a rural habitat used for recreation into a more urbanized and industrialized area. The decision to join Warsaw was made by Hans Hartwig von Beseler, the German governor of then-occupied portions of the Kingdom of Poland (1916–1918), including Warsaw.
