The ruins of the Monastery of Discalced Carmelites are located on a little hill above Zagórz, called Mariemont (345 m a. s. l.). Count Jan Stadnicki was the sponsor of this facility and the construction lasting 30 years began in 1700. The whole monastery complex included the Church of Assumption of the Blessed Virgin Mary, monastery, farm buildings and hospital - shelter for war veterans of noble origins. Monastery was surrounded with a 5-meter high fortified wall with a representative entrance gate. The whole complex was built of yellow sandstone from a quarry situated nearby. In 1722, during the Bar Confederation uprising, the Monastery was cannonaded and partly destroyed. The convent, however, was renovated. On 26th of November 1822, in the Monastery a fire appeared, which ended the period of splendor of the convent. Both accidental fire as well as intentional arson are given as the reason of the fire. Some equipment was managed to save, including large-format paintings that are currently hang in the Sanctuary of Our Lady of Zagórz. In the 1960s, the Curia of Przemyśl handed over the ruins to the Carmelite Order and an attempt to rebuilt was performed. Since 2000, the Commune of Zagórz has been systematically securing the ruins and making it accessible for tourists for sightseeing. It is one of the few fortified monasteries remaining in Poland.
