A monument of architecture of national importance (security number 163 M).
Along with the Jesuit Collegium, the Epiphany Monastery operated over the market square. This center of monastic life arose in 1633, at first as Orthodox, and already in the XVIII century, as Uniate. On the site that was fenced stood a wooden church, a residential building, and outbuildings. Later, a stone complex was built, which has survived to our time, and in its plan resembles the letter “E.”
At the Saint Basil the Great Monastery there was a fraternity, and with it, a school and a printing house. The monastery possessed a charter for stauropegy, which was issued by the Kyiv Metropolitan Petro Mogyla. Several books were printed in the fraternal printing house, including the famous “Grammar of Kremenets” of 1638 – a textbook of the Church Slavic language. In addition, the monastery owned significant land allotments, which the city sued later for urban development.
In 1807, the monastery was moved to the estate of the Reformed Fathers, located on the Dubno suburb, and the Basilian buildings housed the classrooms of the Volyn Gymnasium. Today, in the ancient buildings of the Basilian Fathers, Kremenets Comprehensive School No. 1 named after Halyna Hordasevych operates.
