Tour Piast Tower
Opole’s castle (Zamek) didn’t survive years of invasion or multiple wars, so sadly it is not available for visitors. However what did remain was one of the castle’s towers – Piast Tower, known locally as Wieża Piastowska. It is a sight not to be missed, as it has been well looked after and even turned into a museum. For 6 złotych (local currency), you can head inside for a tour and admire some great views over the city. Check the Piast Tower website for opening times.
