Paczków (German: Patschkau) is a town in Nysa County, Opole Voivodeship, Poland, with 8,226 inhabitants (2004). It is one of the few towns in Europe in which medieval fortifications have been almost completely preserved. Located in the southeastern outskirts of the historical province of Lower Silesia, along the medieval road from Lesser Poland to Klodzko Valley and Prague, Paczków is called "Polish Carcassonne", thanks to its well-preserved medieval fortifications. However, while the famous French Carcassonne is a 19th century reconstruction, all historic buildings of Paczków are authentic.
