The fortress is located on the northeastern slopes of Majevica mountain in the villlage of Gornji Srebrenik, about 5 km away from the city centre. It is built on a steep, almost inaccessible rock, with a deep trench dug underneath, with the only entrance being a small bridge.
History
No current historical sources identify the exact year of its construction or who its constructor was. Earliest records date back to edicts of Stephen II to Ragusa from 1333. It was located on, at the time, important military roads which made it an important strategic stronghold. Already in 1363, king Louis I of Hungary sent an army to Bosnia, led by his palatine Nicholas Kont, which suffered significant losses under Srebrenik. In 1393 it was captured by Hungarian kingSigismund of Luxembourg and within the next decades it changed rulers several times, with Hungarians recapturing it in 1405, 1408 and 1410 respectively. It was then granted as a gift to Serbian despot Stefan Lazarević, but remained in use by the Hungarians as a garrison. King Thomas of Bosnia managed to recapture it by 1433, but already in 1452 it was seized by Đurađ Branković, nephew of Stefan Lazarević, who gave it to Hungarians. By 1462 the entirežupa Usora was under Ottoman control, including Srebrenik. Due to failures in logistics and an epidemic, the Ottoman army had to retreat and Matthias Corvinus managed to seize back Srebrenik. In order to further improve defense against future Ottoman attacks, Matthias created banate of Srebrenik in 1464 and granted it to Nicholas of Ilok who later became the titular king of Bosnia. It is not known when the Ottomans recaptured it, but sometime between 1510 and 1519 is the most likely date. Ever since the Battle of Mohács and up to Treaty of Karlowitz, due to expansion of Ottoman borders, the fortress saw very little military activity. Because of that, it was either completely abandoned or left with only a small garrison. In the 18th century, with Ottoman borders shrinking, it regained its strategic importance. Austrian spies reported it as an old fortress without providing any detailed descriptions. At this time, it was already in dire need of reparations. Some reparations were carried out as early as 1756, but their circumstances and results remain unreported. It finally ceased its use as a garrison in 1835 when the last soldier left it and was mostly abandoned ever after. The mosque, built by the Ottomans in early 16th century, was still maintained in the following years.
