Prosek
Above the narrow gorge of Demir Kapija, the medieval fortress of Prosek guarded the Vardar route through Macedonia. Its steep surroundings made it a formidable stronghold. At the end of the twelfth century it was the seat of the independent lord Dobromir Chrysos, and soon afterwards of Strez. Excavations near the fortress have uncovered a church rebuilt several times, with its last medieval phase dating to the end of the fourteenth or beginning of the fifteenth century.
