Cathedral Basilica of St. Peter and St. Paweł in Poznań, in Ostrów Tumski. The church is huge with a thousand-year history, but you can read about it yourself in e.g. Wikipedia. Despite the fact that it is dedicated to Peter and Paul, the main cabinet altar contains only women. Here is the inscription in the cathedral floor. I can't find info about him, who, when or why. Maybe someone will write in the comment about this... pliz;)) and thanks in advance;))
