Wesoà Âa () is one of the districts of Warsaw, and has been as such since October 27, 2002. Wesoà Âa is located in the south-eastern part of city.
Wesoà Âa received town privileges on December 17, 1968. Then, the town included Wola Grzybowska, Wesoà Âa, Groszówka, Grzybowa, Zielona and Stara Mià Âosna estates. The development of the area was determined by its proximity to three important routes.
The first route, called Stary Trakt (), comes from Grochów, then travels through Okuniew, Stanisà Âawów, and finally through South Podlasie towards Russia. Established near this route was Grzybowa village with Zielona (English: Green) inn and Wola Grzybowa, which now is called Wola Grzybowska.
Near the second route, which comes from Praga, through Kamion, Grochowo, to Mià Âsk Mazowiecki, then through Terespol and Brest, the Mià Âosna village developed. In 1823 on the Stanisà Âaw Staszic's initiative a road was built, called Trakt Brzeski.
The third route was the WarsawâÂÂTerespol Railway, started on September 18, 1867. It comes from Warsaw to Terespol, through Siedlce and à Âuków.
Despite Warsaw growing and annexing new areas, there was no case where two streets shared the same name. The only exception is Wesoà Âa, where many streets have the same name, for example with streets in Warsaw. It presents many difficulties, so addresses in Wesoà Âa are given with a 'Wesoà Âa' annotation.
In the beginning, Wola Grzybowska was a folwark and belonged to the Okuniew municipality. Legend about the name's origin says that the owner of the Wola Grzybowska was a Warsawian starost called Grzybowski. At least from the beginning of the 20th century it belonged to Duke Emanuel Buà Âhak. According to the 1931 census, there were 52 houses in Wola Grzybowska. During World War II Wola Grzybowska was seriously destroyed and later rebuilt. In 1968 it was annexed by Wesoà Âa town. It is host to Warszawa Wola Grzybowska railway station.
The territory Wesoà Âa-Centrum, which now belongs to Wesoà Âa estate, belonged to the Dà Âuga village land properties 500 years ago. In the 17th century it belonged to the Okuniew municipality. Colonization of these areas was related to the building of Kolej Terespolska. Then Wesoà Âa was established as a loading platform for Russian army. After time, it has changed to a rail station (now Warszawa Wesoà Âa railway station). Many houses were built in the area. In 1918 the estate adopted the Wesoà Âa name. Later, the development was closely related to Warsaw. According to the 1937 census, there were 70 habitable buildings. At the end of the 1930s there was a stormy development of villas, due to the climate and virtue of the landscape.
The name derives from the low price of the land - 20 kopecks (popularly 1 grosz) for 1 ell. Sandy, thickly wooded hills weren't the best conditions to colonize these areas. However, now most of the streets remain forested avenues.
Grzybowa in the 17th century was a small settlement whose development was determined by the route from Grochów to Stanisà Âawów. Near this track there was a Zielona inn. According to the 1827 census, in Grzybowa there were only three houses and twelve inhabitants. Around the inn, the village of Zielona started to develop.
In 1895 Zielona was a village in the Varsovian district, in the Okuniew municipality. Zielona's area was 245 morgas and it had 68 inhabitants. In 1795 Austria started to build a customs house there. It was a classical brick building destroyed in 1944. Grzybowa and Zielona were annexed to Wawer municipality. Currently there are beautiful estates located around the forests between the two parabolic dunes. On one of them is placed the Kamieà  Pià Âsudskiego (Pià Âsudski Stone), which commemorates the Polish Military Organisation's field exercises, which took place on April 29, 1917.
Stara Mià Âosna is the oldest estate in Wesoà Âa. Its documented history goes back to the 14th century. Stara Mià Âosna was the szlachta's village. Firstly, the name was Milosina, later Mià Âoà Ânia, Mià Âoà Âna and finally Mià Âosna. Through Mià Âosna runs a route, through which cattle was driven, and through which Warsaw was supplied. Many inns and 'mail' buildings were near the route. In the first half of 19th century, the owner of the majority of the area was prince Franciszek Ksawery Drucki-Lubecki, who was then chancellor of the exchequer. He had a palace there, which was destroyed during Battle of Olszynka Grochowska, in February 1831. After this, Mià Âosna was owned by the Rychà Âowski family. In the 19th and 20th centuries the Mià Âosna area got parcelled out. In the Sà Âownik Geograficzny Królestwa Polskiego (English: Geographic Dictionary of Kingdom of Poland) it stated that in Mià Âosna was a few folwarks (Mià Âosna, Borków, KaczydÃ³à  and à »urawka), nomenclatures (Pohulanka, Janówek and ZakrÃÂt) and one village ZakrÃÂt.
During World War I, in 1915, German Army took over Russian linear defence, which ran on Mià Âosna's hill range. It was called Przedmoà Âcie Warszawy (English: Bridgehead of Warsaw, ). During the Second Polish Republic the area was a prosperous town with summer resort estates, peat's health resort and an airport for gliders. Much was destroyed in World War II.
Until World War I, a large complex of barracks used by the Tsar's army was located near Stanisà Âawów's old road. It was changed into a military training field in the Second Polish Republic's days. Dywizjon Artylerii Pomiarowej z Torunia (English: Artillery Measurement Detachment from Toruà Â) was stationed there, for which was built headquarters, an orchestra building and three accommodation buildings. Between 1949 and 1956 the unit's area became the headquarters of Centralny Oà Ârodek Szkolenia Informacji Wojskowej (English: Army's Information Training Centre) and was kept secret. From 1957 1. Puà Âk Piechoty 1. Dywizji Piechoty im. Tadeusza Koà Âciuszki (English: 1st Infantry Regiment of 1st Tadeusz Koà Âciuszko's Infantry Division) was based here for which a number of blocks were built including an amphitheatre, an allotment's garden ZachÃÂta, a trade pavilion and 'Koà Âciuszkowiec' Club. Today, the estate has 2000 inhabitants and is an open area.
