The key fact here is carried in the name: plac Stanisława Staszica is named for Stanisław Staszic. Let the square work as a small pause rather than a monument demanding a long explanation. While you are standing safely on the pavement, take in the ordinary city life around it: façades along the street, windows and balconies, people passing, and the changing sound of traffic nearby.
Places like this can be easy to hurry through, yet a name gives even an everyday urban corner a human reference point. Here, that reference is Staszic. You can also hear how the Polish name identifies the place directly: plac Stanisława Staszica.
It is a useful detail to carry with you as you continue through Wrocław, especially because street and square names are part of how the city maps memory onto its daily routes. For now, there is no hidden spectacle you need to search for. Simply register the name, the movement around you, and the fact that this open piece of the city is dedicated to Stanisław Staszic.
