One of Poznań's most impressive historic monuments, the The Lesser Basilica of St. Stanislaus, which it became in October 2010, was created as a Jesuit temple in the 17th century. It boasts an interior by a veritable who's who of Roman Baroque artists. The striking interior is 55 metres long, 35 metres wide and 27 metres high, with huge columns providing dramatic light-and-shade effects. Fine specimens of Baroque ornamentation can be found in the chapels of the Holy Cross, which features a 16th-century crucifix, and the Virgin Mary, which has a precious copy of the painting of The Mother of God of Incessant Help. The Basilica hosts organ concerts played on an instrument dating from 1876 on Saturdays at 12.15. Incidentally, the full name is actually 'Bazylika Mniejsza Matki Bożej nieustającej pomocy, Św. Marii Magdaleny i Św. Stanisława Biskupa' - we've gone for the version you've got some chance of pronouncing.
