 On the site of the pagan temple the Benedictine monastery of Holy Cross ("Święty Krzyż") was founded (according to a legend, in 1006, by king of Poland, Bolesław Chrobry, but most sources give the 11th century).The monastery was named after a fragment from Christ' Cross which was supposedly enshrined there, and was a site of frequent pilgrimages.The monastery was destroyed and rebuilt several times throughout its history, with the most significant destruction taking place in the 19th and 20th centuries.
