tbh Germans were cooking with calling old town in Świdnica "Oberstadt" and [no real name at this point] "Niederstadt" it makes way more sense than "Przedmieście"/"Suburb" poles came up with, pretty much nobody uses it outside of railway
especially since Śródmieście right now is this incredibly made up lump of various neighbourhoods and really only commie block neighbourhoods have their own names, one of them even stole it from nearby village lol
