The article takes a closer look at the history of Brzeżany from the time of its uncertain history, i.e. the destruction of the town in the 15th century by Baly-Bej, to its re-founding - already with the rights of a city - by Mikołaj Sieniawski, Grand Hetman of the Crown. The article contains, among other things, a detailed description of the castle erected during Sieniawski's reign, as well as a chapel and two parishes - a Roman Catholic and a Greek Catholic one. A Bernardine church and monastery were also founded by Mikołaj Hieronim Sieniawski. (Source: Tygodnik Illustrowany, Warsaw 1860, T:2, pp. 395-396., after: Digital Library of the University of Łódź)
