In the past Krosno was described as „parva Cracovia”, what means „little Krakow”. This small town with a Renaissance cloth market and an intelectual life at a high level was resembling the royal city with its splendor – Krakow.
The oldest traces of the man in Krosno come from the Palaeolithic era. Krosno was founded by the king Casimir the Great in the 14th century and gained the wealth through its location on the trade route with Hungary. Athough from its beginning Krosno was a trading and craft center its greatest development falls on the 19th century. At this time, at the initiative of Ignacy Lukasiewicz the oil industry was developed. What-is-more during the interwar period Krosno has reached an important economic position – the glass and spinning factory were established here meanwhile the oil industry was succesivelly developed.
The town has retained its medieval urban layout. The market square is surrounded by the 16th- and 18th-century town houses with the Ranaissance arcades. The most beautiful historical monument is the Baroque Oswiecim Chapel in the Gothic Franciscan church, decorated with an exquisite stuccowork by Giovanni Battista Falconi. It contains the tombs of the half siblings Anna and Stanislaw, whose love has ended in tragedy. The legend says that the love between them was so strong they decided to get married despite being related. Stanislaw went to Rome to get the papal permission, but his beloved has died having not received any message from him. The parish church on the opposite side of the market square was built in the 16th century and comprises the Sarmatian paintings and the three bells from 1639. One of them, the Urban is the second largest bell in Poland next to the Sigismund Bell in Cracow. The former Bishop’s Palace houses the interesting District Museum with a collection of kerosene lamps, work of art by local artists, handicrafts etc.
