A very beautiful Serbian monastery on Fruska Gora. He has a lot to do with Russia. In addition to the main St. Nicholas Church, there is the church of Seraphim of Sarov, the Nativity of the Virgin and, uncharacteristically for Serbia, the Transfiguration Monastery.
Services are provided daily. Many people come to the icon of the Theotokos "Troeruchitsa". It's nice to take a walk.
