Rmanj Monastery: The Rmanj Monastery () is a Serbian Orthodox monastery dedicated to Saint Nicholas and located in Martin Brod in north-western Bosnia and Herzegovina, at the left bank of the Unac River near its confluence with the Una.  It was probably founded in the late 15th or early 16th century.  After the Ottoman Empire's conquest of the area, the monastery was temporarily abandoned in 1578.  Bosnian Beylerbey Telli Hasan Pasha had the Rmanj Monastery renewed as a seat of his brother, Orthodox monk Gavrilo Predojević.  In the early 17th century, it became the see of the Serbian Orthodox Metropolitanate of Dabar-Bosnia, and it remained in this capacity for about 110 years.  After the monastery was burned down by the Turks in 1663, it was later rebuilt and reoccupied in 1737.  It was burned down again during the Austro-Turkish War of 1787–1791.  Ottoman authorities allowed the renovation of the monastery in 1863, and it was rebuilt in two years.  It was badly damaged during the anti-Ottoman uprising in Bosnia in 1875 and 1876.  Next year, Arthur Evans visited Rmanj (spelled as "Ermanja" by him), and in one of his letters, he described the damage inflicted on the monastery's church by troops under a Bosnian Muslim feudal lord.  Once more, the monastery was repaired in 1883.
