In the place of today's Gen. Kazimierza Pułaskiego residential estate (previously, until 1983, Władysława Eugeniusza Sikorskiego) in 1887-1888, the Infantry Barracks were established, the so-called “Jarosław Swedish Camp” (Schwedenlager). This name probably stemmed from the fact that in 1888-1905 the regiment's head was Oscar II, and then in 1908 his son Gustaf V, i.e. kings of Sweden, Norway, Goths and Venedicts. The Infantry Barracks, called Baracken Kaserne, included the whole complex which consisted of several brick residential buildings, warehouses and stables.
From 1922 the barracks were occupied by 3rd Legions Infantry Regiment which was established in September 1914. The Regiment became part of 2nd Brigade of the Polish Legions with which it passed the entire war campaign. After the remnants of this regiment were broken up by Germans until the capitulation, they took part in the defence of the Modlin fortress.
In memory of this event, on September 30,1929, in the 15th anniversary of the regiment foundation, a solemn consecration of the Carpathian cross took place. The cross was a copy of a seven-metre high cross erected in 1914 by legionnaires on the so-called Legionary Pass (the pass in the Eastern Carpathians with a height of 1,110 m above sea level, in the territory of today's Ukraine, above the village of Rafajłowa, between the Taupiszyrka peak (1503 m above sea level) in the massif of Sywula and Połonina Czarna.
The barracks at Kościuszki Street were still in the hands of the army after World War II.
