The building comes from the turn of the 11th and 12th centuries. It was created in a place where-according to a legend- St. Adalbert preached his sermons.
In the 17th centuries church was rebuilt and furnished in the spirit of baroque – you can see it for example on ornamental dome.
In the underground of the church you can find some museums.
Building located on Main Square Market hides many treasures- it’s worth to take a moment and see them with your own eyes.
