Mrkonjići (Serbian: Мркоњићи) is a village in the municipality of Trebinje, Republika Srpska, Bosnia and Herzegovina.[1]
In this village Basil of Ostrog was born as Stojan Jovanović in 1610. At a young age, he entered the nearby Zavala Monastery, from where he continued to Tvrdoš Monastery, and to various centers of the Orthodox church around the world.[2] At the site of his birth house, a church was built in the 1990s and later expanded into Mrkonjići Monastery. Its annual celebration of St Vasilije on May 12 brings numerous visitors to the village.[3] [4]
