Belogradchik Fortress, the Stronghold Set Among Natural Rock Walls
Belogradchik Fortress, known locally as Kaleto, stands on the northern slopes of the Balkan Mountains beside the north-western Bulgarian town of Belogradchik. Begun in Roman times and enlarged by Bulgarian tsars and Ottoman engineers, it is one of the best-preserved strongholds in Bulgaria and a cultural monument of national importance. Together with the Belogradchik Rocks it draws most visitors to the region.
This fortress needed walls on only two sides, because towering natural rocks, up to 70 metres high, guarded the rest. Its builders simply let the mountain do most of the work.
The history of Belogradchik Fortress
The first fortress was built when this region belonged to the Roman Empire; German Wikipedia places it between the first and third centuries CE, while the Polish article names the third. The builders used the natural rock formations as protection. Walls were raised only on the north-west and south-east sides, because the rest of the courtyard is enclosed by rocks up to 70 metres high. At first the fortress was mainly a lookout rather than a purely defensive work, and it is said to have watched the road from Ratiaria. Excavations found wall foundations, pottery, iron spear and arrow heads, and coins of the emperors Vespasian, Trajan, Septimius Severus, Gordian III and Decius.
In the fourteenth century Tsar Ivan Sratsimir of Vidin extended the old fortress, building fortified garrison posts in front of the existing rock masses. Under his rule it became one of the most important strongholds in the region, second only to his capital fortress, Baba Vida in Vidin. The fortress name first appears in the chronicle of a Hungarian annalist describing the campaign of Louis I of Anjou, who took Vidin in June 1365; the record lists the stronghold of Fehérvár, usually identified with Belogradchik, among the places captured afterwards. Rebellious Bulgarians drove the garrison out in 1369.
The Ottomans captured the fortress in 1396 and partly destroyed it, but they later had to expand it because of growing hajduk and insurgent activity in the area. The biggest changes came between 1805 and 1837, when the fortress was reorganised and enlarged under the guidance of French and Italian engineers. New walls of stone blocks and mortar, gun platforms, firing steps at the loopholes, underground stores for ammunition and food, and a belt of buried wooden stakes strengthened its defences. Inside there were guardrooms with hearths, a granary, a wheat and salt mill, a stable, a well and two rainwater cisterns.
The fortress played an important part in the Ottoman suppression of the Belogradchik Uprising of 1850. In 1862 the so-called Suleiman fortification was added to strengthen the western part, and during the Russo-Ottoman War of 1877–1878 it was besieged by Russian and Romanian troops. It was last used in warfare during the Serbo-Bulgarian War of 1885. Later restored, it is now a cultural monument of national importance managed by the local historical museum, and it belongs to the Hundred National Tourist Sites of Bulgaria.
