Then, the town included Wola Grzybowska, Wesoła, Groszówka, Grzybowa, Zielona and Stara Miłosna estates.

Near the second route, which comes from Praga, through Kamion, Grochowo, to Mińsk Mazowiecki, then through Terespol and Brest, the Miłosna village developed.

In 1823 on the Stanisław Staszic's initiative a road was built, called Trakt Brzeski.

Legend about the name's origin says that the owner of the Wola Grzybowska was a Warsawian starost called Grzybowski.

At the end of the 1930s there was a stormy development of villas, due to the climate and virtue of the landscape.

Grzybowa in the 17th century was a small settlement whose development was determined by the route from Grochów to Stanisławów.

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.

In the Słownik Geograficzny Królestwa Polskiego (English: Geographic Dictionary of Kingdom of Poland) it stated that in Miłosna was a few folwarks (Miłosna, Borków, Kaczydół and Żurawka), nomenclatures (Pohulanka, Janówek and Zakręt) and one village Zakręt.

During World War I, in 1915, German Army took over Russian linear defence, which ran on Miłosna's hill range.

It was called Przedmoście Warszawy (English: Bridgehead of Warsaw, German: Bruckenkopf Warschau).

Until World War I, a large complex of barracks used by the Tsar's army was located near Stanisławów's old road.

Between 1949 and 1956 the unit's area became the headquarters of Centralny Ośrodek Szkolenia Informacji Wojskowej (English: Army's Information Training Centre) and was kept secret.

Tadeusza Kościuszki (English: 1st Infantry Regiment of 1st Tadeusz Kościuszko's Infantry Division) was based here for which a number of blocks were built including an amphitheatre, an allotment's garden Zachęta, a trade pavilion and 'Kościuszkowiec' Club.
