It's often interesting to explore differing beliefs and values. A trip to Church of the Holy Saviour is a good way to experience one of the local religions and ways of life.
This house of prayer in Zwierzyniec is well-liked by many travelers, so make a spot for it on your schedule. Don't think that's all there is to do here, though. There are many more spots ready for you to experience after Church of the Holy Saviour. Main Market Square, Wawel Castle, and Oskar Schindler Factory are close by.
