In the historical context the Three Crosses Square [Plac Trzech Krzyży] appears to be strongly branded by the transport function of the Royal Route axis [Trakt Królewski] and by religious elements that physically make up the identity of the place: the building of St. Alexander church and cross monuments - the identifier of the square and part of the lost complex of 28 chapels of Kalwaria Ujazdowska from the eighteenth century.
The concept of extending the central square composition is an extension of the pedestrian space of four streets: Nowy Świat, Bracka, Aleje Ujazdowskie and Mokotowska. This means that pedestrian connections between these streets may be achieved through the square without having to cut into vehicle transport routes within the area of the square. This shortens the time distances of all pedestrian connections and leads pedestrians directly into the space of the square.
The aim of rebuilding the frontage of the square destroyed during the war was to help restore the character of urban interior, but the western frontage was deprived of its historical run. The project involves restoration of the old run of the frontage with a row of oaks. On the other hand, a modern interpretation of the form of a quarter garden is to be a response to the historical greenery arrangement of the square.
