In 1171 the Bishop Gedeon founded a collegiate church under the invocation of the Assumption of the BVM located on Wzgórze Zamkowe (Castle Hill). It was a Romanesque-style temple. It was rebuilt and extended several times throughout ages to finally resemble an early Baroque three-aisle basilica. In the interiors of the Cathedral it is worth seeing the Gothic triptych depicting a crowning ceremony of the Mother of God and the baroque main altar designed by Fontana.
There you can also find a painting depicting the Gracious Mother of God of Kielce with her Child. Tourist may also see the cathedral treasury and descent into the underground crypt of the bishops of Kielce.
