12 kilometers northeast of Konin is the largest temple in Poland. St. Mary's Sanctuary cult center, which was developed in the second half of the 19th century, is currently one of the most visited pilgrimage places in Poland (1.5 to 2 million pilgrims come here annually). St. Mary's Sanctuary often called the "Częstochowa of the North", attracts like a magnet of pilgrims who want to see with their own eyes the miraculous image of Our Lady of Licheń - the Sorrowful Queen of Poland.  The painting is a copy of the image of Mother God of Rokita, moved from the forest chapel to the neo-gothic church of Saint. Dorota, then in 2006 to the Basilica. The sanctuary impresses primarily with its huge dimensions: 120 m long, 77 m wide, tower height is 141.5 m. In turn, in the belfry, next to the Basilica hangs the largest bell in Poland - "Mary Mother of God" with a mass of 14.7 tons. From July 2010 on the second and third floor of the basilica there is a Museum named after priest Józef Jarzębowski, MIC, transferred from Fowley Cort in Great Britain.
