The fortification of Medun dominates the Kuči ancient territory, sitting on the pick of the rocky hill of Kučka Krajina, about 13 kilometers far from Pogdorica.

Throughout its existence from the 5th or 6th century B. C. Medun Frotress, as a fortification structure, has gone through the several phases of development and transformation: It was built as a Pergamon-type Illyrian castrum, with a fortified acropolis in the upper castrum zone and a commercial agora situated in the area of perimeter ancient walls of the lower castrum zone. Those walls were built as Cyclopean masonry, and part of those walls are still existing. This type of stonework is also found in other Illyrian castrums such as Nedino, Sidron, Ansium, Aserija, Vravarija, Daorsona, Zvonigrad, Studenica, Martinović Gomile, Mokro etc., and for some of those castrums there is historical information that dates up to 2000 years B.C. Before the 7th century A. D., most probably during Justinian, Eastern Roman Empire construction period, the fortification was reconstructed on the remains of the partially destroyed ancient castrum. The Primary Medun Medieval Fortress was built in the upper fortress zone together with the acropolis and originally small church. The perimeter wall was additionally built around the acropolis support, as well as two fortress towers, a structure called "kurija" and a gateway. The appearance of firearms and artillery and the Turkish conquests in the 15th century got the fortification to transform into the Secondary Medun Medieval Fortress whose towers and walls were reinforced by the construction of Branič-kula (Defense Tower) on the acropolis, construction of a barbican in the lower zone and cingulums in either Zone of the fortress. This made the Secondary Medun Medieval Fortress a Castle nestle data strategic location (with respect to the structures that have a sacral building and "kurija" and as a Rudimentary Castle). Therefore until the eighties of the 19th century, the period in which Medun Fortress operated as an active fortification, it was used for this purpose.

Only Kuči managed to conquer it on three occasions by attacking at night and thanks to their excellent knowledge of the fortress reef configuration. In the period following the Middle Ages, Medun Fortress was released to Turkish control four times due to political, or tactic reasons.

During its existence, Medun Fortress was demolished several times. The earthquakes which damaged Medun were in 518, 1563 and 1667. Besides the demolishing that the fortress sustained in the earthquakes, it is well-known that it suffered demolishing from mining in 1876. Although Medun Fortress (or Meteon, or Medion, or Medunkale) was not a large fortification nor it was a fortification significant to the state, the structure of this fortification has gone through a complex development process that happened in several phases and a rather long, since the ancient times, and unusually turbulent history of its existence.
