The Bernardine church and monastery complex in Dukla is a center of worship of St. Jan Dukla and since 2009 has the status of a sanctuary. In a brick late baroque church, in the chapel of St. John, the relics of the saint are transferred here from Lviv. In the temple you can also see the works of famous Lviv artists: sculptures by Fabian Fesinger and the polychrome of Tadeusz Popiel. In front of the church there are eighteenth-century statues of Bernardine saints: Francis of Assisi and Bernard of Siena.
The church was built in 1761-1764 on the site of an earlier wooden temple. In the next decade it was expanded. The adjoining four-wing monastery building was erected in 1742-1750. In 1835, the church and monastery complex was almost completely digested by fire and it was not until the turn of the 19th and 20th centuries that its original appearance was restored.
There are other places of worship of Saint. John, who is looked after by the fathers of the Dukla monastery: the hermitage situated in the forests on Trzciana and Złota Studzienka on the slopes of Cergowa Mountain.
