The Belogradchik Fortress,also known as Kaleto, is an ancient fortress located on the north slopes of the Balkan Mountains, close to the northwestern Bulgarian town of Belogradchik and is the town's primary cultural and historical tourist attraction, drawing, together with the Belogradchik Rocks. It is one of the best-preserved strongholds in Bulgaria and a cultural monument of national importance.
The fortress's walls are over 2 metres thick in the foundation and reaching up to 12 m in height. Three separate fortified yards exist that are connected with each other through gates. The fortress has a total area of 10,210 square metres.
The initial fortress was constructed during the time when the region was part of the Roman Empire. The rock formations in the area served as a natural protection, as fortified walls were practically only built from the northwest and southeast, with the yard being surrounded by rocks up to 70 m high from the other sides.
Initially, the Belogradchik Fortress served for surveillance and not strictly defense. The Bulgarian tsar of Vidin, Ivan Stratsimir extended the old fortress in the 14th century, building fortified garrisons in front of the existing rock massifs. During Stratsimir's rule, the Belogradchik Fortress became one of the most important strongholds in the region, second only to the tsar's capital fortress of Vidin, Baba Vida.
During the Ottoman conquest of Bulgaria, the fortress was captured by the Ottomans in 1396. They were forced to further expand the stronghold due to the intensified hajduk and insurrectionist activity in the region.
Considerable changes to the fortress were made in the early 19th century. These changes were typical for the Ottoman castle architecture of the period, a full reorganization being carried out, as well as additional expansion. Typically European elements were added to the Belogradchik Fortress owing to the French and Italian engineers that participated in the expansion.
The stronghold had an important role in the Ottoman suppression of the Bulgarian Belogradchik Uprising of 1850. It was last used in warfare during the Serbo-Bulgarian War in 1885.
References:The Château de Chantilly comprises two attached buildings: the Petit Château built around 1560 for Anne de Montmorency, and the Grand Château, which was destroyed during the French Revolution and rebuilt in the 1870s. Owned by the Institut de France, the château houses the Musée Condé. It is one of the finest art galleries in France and is open to the public.
The estate"s connection with the Montmorency family began in 1484. The first mansion (now replaced by the Grand Château) was built in 1528–1531 for the Constable Anne de Montmorency by Pierre Chambiges. The Petit Château was also built for him, around 1560, probably by Jean Bullant. In 1632, after the death of Henri II, it passed to the Grand Condé who inherited it through his mother, Charlotte Marguerite de Montmorency.
Several interesting pieces of history are associated with the château during the 17th century.
