St. Naum Monastery
St. Naum Monastery is a monastery built from the 10th century in Byzantine architecture. It was founded by St. Naum of Preslav (830-910), a disciple of Saints Cyril and Methodius. In the 16th century, during the Ottoman occupation, new buildings were constructed on the foundations of the original building. However, a part of them was destroyed in a fire in 1875.
