The area extends eastward from the Three Crosses Square and covers the broad parkland and housing estates surrounding Frascati and Nullo streets, located between the Polish parliament building, the Warsaw Stock Exchange and the National Museum.

[1] The history of Frascati dates back to 1779, when a road was constructed from Wiejska Street to the private palace of prince Kazimierz Poniatowski (1721–1800), lord chamberlain of the Polish–Lithuanian Commonwealth and brother of king Stanisław II Augustus.

[7] The subsequent owners of the property, the aristocratic Branicki family, built a larger Renaissance Revival-styled chateau, which became known as the Red Palace (Czerwony Pałac) due to its clinker brick exterior.

The hilly garden contained many novelty and oriental structures, including a 15-metre minaret, a Chinese pavilion and a Middle Eastern outbuilding, which was dubbed by locals as the "Imam House" (Domek Imama).

[12] The Frascati neighbourhood was inhabited by many notables and dignitaries, among them nobles, financiers, business tycoons, generals and statesmen like the much-detested Nikolay Novosiltsev, the council commissar in the Congress Kingdom of Poland.
