It is the seat of the Trebinje-Mrkan Bishopric. Petar Palić acts as bishop to the Trebinje-Mrkan Bishopric as well as the Mostar-Duvno Bishopric.
The cathedral is named after the Nativity of Mary. The construction of the Church of the Nativity of Mary began in 1880. The building was completed and blessed on 7 June 1884. On the occasion of dedication by Pope Leo XIII, a great image of the Virgin Mary was donated to the church with baby Jesus. During the Second World War the church was reduced to a dilapidated state and repairs were necessary that were completed in 1918.
