History
Mezek Fortress is a medieval Byzantine border fortress in Bulgaria, built during the eleventh and twelfth centuries on the frontier west of the modern village of Mezek. The Byzantine Empire, the medieval eastern Roman state, used it to guard the territory between the Maritsa and Arda rivers.
Byzantine Frontier Fortress
Archaeological evidence places construction at the end of the eleventh or the beginning of the twelfth century, probably during the reign of the Byzantine emperor Alexios I Komnenos. The fortress later stood within a contested borderland between the Byzantine and Bulgarian Empires, a major medieval struggle for control of southeastern Europe. Ceramics from the thirteenth and fourteenth centuries show continued activity during these later phases.
Mezek Fortress has been identified with Neoutzikon, a stronghold mentioned by the Byzantine historian Niketas Choniates. In 1193, the Byzantine emperor Isaac II Angelos suppressed a rebellion at Neoutzikon led by his cousin Constantine Angelos Doukas. Doukas, governor of Philippopolis, the medieval name for Plovdiv, had proclaimed himself emperor. His own men captured him before he reached Adrianople, now Edirne, and the capture encouraged Bulgarian rebels who were opposing Isaac II.
The fortress was also associated with the medieval boundary between the dioceses of Philippopolis and Adrianople. The nineteenth-century Czech historian Konstantin Jireček identified the ruins with Neoutzikon. This interpretation connected Mezek to the political and ecclesiastical geography of the Byzantine frontier.
Ottoman Conquest and Archaeological Study
Byzantine and Bulgarian control gave way to the Ottoman Empire, the Turkish imperial state that conquered much of the Balkans during the fourteenth and fifteenth centuries. Ottoman forces conquered the fortress in the second half of the fourteenth century, and it remained in operation until the surrounding region came under Ottoman rule.
Architect Aleksandar Rashenov led the first archaeological investigations in the 1930s, excavating parts of the site, documenting its fortification system, and examining limited areas within the enclosure. More extensive excavations in 1983 clarified the fortress plan, defensive arrangements, and date. In 1900, Ottoman authorities demolished part of the fortress so that its stones could be reused for barracks in Svilengrad.
Conservation and restoration work took place in 1963, 1973, and 2007. The fortress was declared a national antiquity in 1927 and an architectural monument of national cultural significance in 1968. It also forms part of the Kaleto Natural Landmark, established in 1976 to protect the fortress and surrounding rock formations. Locally, the site is called Kaleto, after the hill on which it stands, and it is regarded as the best-preserved fortress in the eastern Rhodope Mountains.
Remains
The fortress stands about 210 metres above sea level on an elongated terrace at the foot of the northeastern Rhodope ridge known as Gorata or St Marina. Its irregular quadrilateral enclosure covers about 6,500 square metres and measures approximately 110 by 60 metres. The surviving walls and projecting towers define a compact defensive layout on the terrace.
Defensive Enclosure
Walls and Western Entrance
The walls are 1.90 to 2.50 metres thick and consist of rubble stone bonded with white mortar. Three horizontal belts of brick decorate their outer faces. The western entrance occupies the northern end of the west wall, where it was placed in a deep recess and protected by a tower. The walls were originally crowned by battlements, a crenellated defensive parapet. These survived until 1900. The northern walls now reach only the interior ground level, while the southern, western, and eastern walls survive to the height of the platform that supported the battlements.
Projecting Towers
Nine round towers project more than half their diameter beyond the walls, and each rises more than 10 metres. Five stand along the vulnerable south wall, including two corner towers and three front towers. Two are positioned on the west wall, one beside the main entrance, while one tower stands on each of the north and east walls.
The large southwestern corner tower is particularly well preserved. It had three floors, with battlements on the upper two. The floors opened toward the interior, enabling defenders to maintain a circular field of fire and continue resisting even if attackers entered the enclosure. A military installation from the Cold War occupies the easternmost tower.
Interior Finds and Storage
Excavations within the fortress recovered numerous ceramic fragments and vessels, stone millstones, and other household objects. Two granaries containing charred wheat provide evidence of stored food within the fortified settlement.
Mezek Tomb
Thracian Burial Monument
About 600 metres east of the fortress stands the Mezek Tomb, identified as Bulgaria’s largest Thracian beehive tomb. A beehive tomb, also called a tholos tomb, is a circular burial monument with a corbelled chamber shaped like a beehive. Its location forms part of the archaeological landscape surrounding the medieval fortress.
