The construction of the St. Nicholas basilica in Bochnia began at the beginning of the fifteenth century on the site of an earlier, probably romanesque temple. The gothic church was completed before 1447, when the temple was burned in a great town fire. It was reconstructed but unfortunately re-ignited in 1461. After second fire, at the end of the fifteenth century, the still present church was erected. After the devastation of the Swedish Deluge, the church received a baroque decor that survived until 1901-1905, when the church was regothisated under the direction of architect Tadeusz Stryjeński. In the nineteenth century, north and south porches, a vault over the sacristy and a neo-gothic ridge turret, were added.
Basilica of St. Nicholas is a gothic, three-nave church with a facade from the end of the fifteenth century, supported by two buttresses, crowned with a stepped gable and decorated with blendes and a diamond frieze. It has no equivalent in the architecture of Małopolska, however, it resembles gothic churches in northern Poland. On the eastern side church is finished with a narrow, polygonal chancel to which the sacristy was added from the north. In the chapel of St. Kinga can be seen fresco from the fifteenth century. Next to the church is a free-standing, wooden belfry from the 16th century.
