Grunwald Square was designed between 1920 and 1922, as part of the planning road system near Warsaw Citadel. Its authors were Antoni Jawornicki and Józef Jankowski. 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][2]
