[1] Grunwald Square was designed between 1920 and 1922, as part of the planning road system near Warsaw Citadel.

It was originally envisioned as a half-circle with the five-way crossing of newly planned streets, then named Marynarki, Lotnictwa, Kawalerii, and Artylerii.

The square and nearby roads began construction in the 1930s, however, the works on the project were halted before its full completion.

[1][3] At the square, there is the Monument to the Military Endeavour of Polish Americans made by Baltazar Brukalski and Andrzej Pityński, unveiled on 14 August 1998.

It was proposed by the Polish Army Veterans' Association in America, and made by Baltazar Brukalski and Andrzej Pityński.
