Sà Âuà ¼ewiec () is a neighbourhood, and a City Information System area, in Warsaw, Poland, within the Mokotów district. It is a mixed high-rise area with residential and office buildings, with a population estimated at around 31,000 in 2025. Its part forms a financial district, together with the nearby neighbourhood of Ksawerów, colloquially referred to as Mordor. It includes the headquarters of numerous domestic companies, and branches of many multinational corporations. The neighbourhood also features the Warszawa Sà Âuà ¼ewiec railway station. The area is part of the western half of the district, known as the Upper Mokotów.
The oldest known records of Sà Âuà ¼ewiec, then a village, date to 1378. It was incorporated into the city of Warsaw in 1938, and was destroyed in 1944, during the Second World War. The neighbourhood was re-developed as a major industrial district in the 1950s, known as Sà Âuà ¼ewiec Przemysà Âowy (Industrial Sà Âuà ¼ewiec), and in the 1990s, it transformed into the largest financial district in Poland, and remained as such until 2019. Afterwards, the rented office spaces in the area began to decline, as it converted into a residential district.
The name Sà Âuà ¼ewiec comes from the nearby neighbourhood, and historically a village, of Sà Âuà ¼ew, known until the 16th century as Sà Âuà ¼ewo. It originates from the archaic Polish word sà Âuà ¼, an equivalent to modern sà Âuà ¼yÃÂ, which means to serve. It came from the fact that historically the area was inhabited by serfs, peasants who served the local noble families. Sà Âuà ¼ewiec itself was part of the agricultural estate centred around Sà Âuà ¼ew.
Sà Âuà ¼ewiec was settled alongside the Sadurka stream. Its oldest known records in documentation come from 1378, when, it was listed as one of 17 villages of the agricultural estate of Sà Âuà ¼ew. At the time, it was a small farming community attached to the nearby village of Sà Âuà ¼ew, with a farmland area of 9 voloks (1.616 km<sup>2</sup>), making it the largest on the list. In 1411, Sà Âuà ¼ewiec was granted the Kulm law privileges by duke Janusz I the Old, ruler of the Duchy of Warsaw. By 1580, it was inhabited by the petty nobility. In 1678, Sà Âuà ¼ewiec and Sà Âuà ¼ewo were bought by Stanisà Âaw Herakliusz Lubomirski becoming part of his landed property.
In 1886, the Fort VIIA "Sà Âuà ¼ewiec" was built near the village, as part of the series of fortifications of the Warsaw Fortress, constructed around the city by the Imperial Russian Army. The objective of the fort had been the protection of the nearby road leading to the town of Puà Âawy, now forming Puà Âawska Street. It was decided to be decommissioned in 1909 and partially demolished in 1913. Currently, the building is located within the City Information System area of Sà Âuà ¼ew.
In 1903, the Sà Âuà ¼ewiec narrow-gauge railway station, operated by the Grójec Commuter Railway, was opened, as part of the line between stations of Warszawa Mokotów and Nowe Miasto nad PilicÃÂ. It operated until 31 July 1971, and was located to the south-east of Sà Âuà ¼ewiec, near the current intersection of Puà Âawska, and Dolina Sà Âuà ¼ewiecka Streets, within the modern boundaries of North Ursynów.
Between the 1920s and 1930s, the course of the Sadurka stream, which flowed through Sà Âuà ¼ewiec, was artificially altered to bypass the area.
Between 1925 and 1939, the Sà Âuà ¼ewiec Racecourse was built at 266 Puà Âawska Street, to the south of the village. Upon its opening, it became the largest and most modern horse racing venue in Europe, with its main circuit measuring 2,300 m. It begun hosting the Great Warsaw Race, the most prestigious horse race in Poland. During the Second World War, the race track was captured by the invading German forces in the siege of Warsaw. While under the occupation, the race track served as an airstrip for the fighter aircraft of the German Air Force. In July 1944, between 600 and 800 German soldiers were stationed there. On 1 August 1944, on the first day of the Warsaw Uprising, Polish resistance participants from the Karpaty Battalion of the Baszta Regiment, carried out an unsuccessful attack on the airstrip, suffering heavy casualties. Later that day, in retaliation, the German forces organised an execution at the racecourse, killing captured partisans and a group of civilians, rounded up in the nearby Sà Âuà ¼ew. The racetrack is currently located within the boundaries of North Ursynów.
On 27 September 1938, Sà Âuà ¼ew and Sà Âuà ¼ewiec were incorporated into the city of Warsaw, becoming part of the Mokotów district. The neighbourhood was completely destroyed in 1944 by the German officers, during the Second World War, as part of the destruction of Warsaw. The only surviving historical structure is a small Catholic shrine located at the Bokserska Street.
In 1951, the area of Sà Âuà ¼ewiec, Zbarà ¼, and Wyczóà Âki, was designated to become the Industrial and Storage District of Sà Âuà ¼ewiec (Polish: Dzielnica Przemysà Âowo-Skà Âadowa âÂÂSà Âuà ¼ewiecâÂÂ), later known as Sà Âuà ¼ewiec Przemysà Âowy (Industrial Sà Âuà ¼ewiec). It was envisioned to feature 60 factories and industrial plants. The construction begun in 1952, and utilized the large panel system technique, marking it as one of the first instances of its usage in Poland. The designated area covered around 2.6 km<sup>2</sup> (1 sq mi). In the early 1970s, around 20,000 people were employed in the industrial district.
In 1951, the Institute of Organisation and Mechanisation of Construction was founded. It was renamed in 1973 to the Institute of Construction Mechanisation, and again in 1986, to the Institute of Mechanised Construction and Rock Mining, becoming a research facility for the mechanisation of construction, and development of machinery for construction, road, building materials industry and rock mining. It had its headquarters at 6 and 8 Racjonalizacji Street. It operated until 2023, when it merged with the Institute of Precision Mechanics to form the Warsaw Institute of Technology, with its headquarters in the à »oliborz district.
In 1953, the Mokotów trams depot was opened at 27 Woronicza Street In 1959, the Woronicza bus depot was also opened on the other side of the road, at 29 Woronicza Street. In 1961, the neighbourhood was connected to the tram network, with tracks built alongside Woà Âoska and Marynarska Streets, and ending with a turning loop near Suwak Street. In 1962, the Warszawa Sà Âuà ¼ewiec railway station, was opened at Logarytmiczna Street.
Between 1960 and 1965, the housing estate of Sà Âuà ¼ewiec-Prototypy, was built to the east of the industrial area, between Lotników Avenue, Modzelewskiego Street, Bokserska Street, and Obrzeà ¼na Street, with Rzymowskiego Street as its main axis. Consisting of high-rise multifamily buildings, the neighbourhood was constructed as a test ground for new technologies and urbanist solutions, such as various large-panel-system building techniques. The observation of various types of building techniques during and after their construction was intended to allow for the improvement of new projects, comparison of existing ones and implementation of cost-reducing solutions. It was the first and the largest research ground of its kind in Poland. The neighbourhood was designed with modernist apartment buildings. The neighbourhood was intended to provide housing for the employees of numerous factories in the nearby industrial district, located within walking distance of it. Currently, it is located within the City Information System area of Sà Âuà ¼ew.
In 1961, the headquarters of the à Âukasiewicz Institute of Ceramics and Building Materials of the à Âukasiewicz Research Network, then known as the Institute of Glass and Ceramics Industry, were moved to 9 PostÃÂpu Street in Sà Âuà ¼ewiec. Currently, it is a national research institute of processing of nonmetal resources, including the manufacture of ceramics and building materials, mineral binding agents, and concrete.
On 4 October 1996, the district of Mokotów was subdivided into the City Information System areas, with Sà Âuà ¼ewiec becoming one of them. In 2001, the administrative neighbourhood of Sà Âuà ¼ewiec Poà Âudniowy (South Sà Âuà ¼ewiec), governed by an elected neighbourhood council, was established in an area covering southern Sà Âuà ¼ewiec and south-eastern Sà Âuà ¼ew.
In the 1990s, the manufacturing industry left the area, leading to the emergence of a financial district, with the development of large office complexes, eventually becoming the largest in Poland. In 1992, Curtis Plaza, located at 18 Woà Âoska Street at the boundary of Sà Âuà ¼ewiec and Ksawerów, became one of the first office buildings constructed in the area. It was considered a prime example of postmodern architecture in the city, and was eventually demolished in 2024. The Mokotów Business Park, at Domaniewska Street, built between 1995 to 2001, became another example of an office building complex built in the neighbourhood. In 2000, Westfield Mokotów (originally known as Galeria Mokotów), one of the largest shopping centres in the city, was opened at 12 Woà Âoska Street, on the boundary of Sà Âuà ¼ewiec and Ksawerów. By 2019, the area included 83 office buildings, which were mostly constructed without city oversight and contributed to the development of an office monoculture. In 2015, the area had been estimated to have between 80 and 100 thousand people commuting to work there, in comparison to around 15,000 residents. The large number of daily commuters, together with local road systems not designed for such volume of traffic, caused regular traffic congestion and lack of availability of parking space in the area, leading to the financial district being colloquially known as Mordor and Mordor on Domaniewska Street. The name referenced Mordor, a fictional location, and personification of evil, from the 1954 fantasy novel The Lord of the Rings written by J. R. R. Tolkien. In 2020, following the petition of local inhabitants, two small streets in the neighbourhood were named after Tolkien and Gandalf, one of the main characters from the book. The traffic situation eventually improved in the 2020s, with the development of new roads, improvement of public transit, and decrease of office space presence in the area.
By the 2010s, almost all of the historical industrial objects were deconstructed and replaced by new office and residential buildings. One of the last remaining artefacts in the neighbourhood, dating to its industrial era, is the Memorial of the Builders of Industrial Sà Âuà ¼ewiec, a socialist realist sculpture depicting a bricklayer, dedicated to people who worked on the construction of the district in the 1950s. It is placed in front of the office building Park Rozwoju, at Suwak Street. Its author and history remain unknown. Until the 2010s, it was placed behind one of the warehouses in the area, and was moved to its current location in 2015.
The high-rise residential buildings begun being constructed in the former industrial area of Sà Âuà ¼ewiec in the 1990s, alongside office buildings. While, the region was dominated by office spaces, and considered the largest financial district in Poland, it begun losing its status to the Wola district in 2019, with the last office building being built there in 2020. Since then, the number of rented office spaces begun to steadily decrease, as the neighbourhood begun transforming into a housing area, with the development of new housing estates throughout the early 2020s, with the estimated population of 31,000 in 2025.
In 2019, the Tram Tradition Chamber was opened in the Mokotów tram depot as a museum of the history of trams in Warsaw.
In December 2024, the Suwak Linear Park was opened, stretching alongside Suwak Street, from Logarytmiczna to Woronicza Streets, on an area of 2 ha.
