Unlike other forts in the Una river valley, Rmanj is located in a flatland, at the confluence of the Unac into the Una. It is believed to have been built in the 14th or the 15th century, and was taken by the Ottoman Empire in 1524. The only preserved part of the fortification is the circular tower.^[1]

It is believed to be located in the place of an early medieval castrum of Ermin or Ermen, also referred to in sources as Herman, Hermanj, Ermain, and Sermil, and the earliest mention of this was 1431. There was also a toponym of Conuba or Konoba in use for an unknown place nearby, first in 1396, which may have been the same town or a reference to the nearby Rmanj Monastery. The fortification was owned by the House of Celje and the House of Frankopan.^[2]

The site was declared a national monument in 2016.^[3][4]
