The temple was extended from 1890 to 1902 when a chapel of St. John of Dukla was built and the main nave was enlarged. Also monastery building was added. The interior dates back to the turn of the 19th century. The paintings of Tadeusz Popiel present scenes from life of St. John of Dukla. There is a silver coffin with relics of St. John. Pope John Paul II came to Dukla on 9th of August, a day before the canonization event and he spent a night in the monastery.
