Kaposszentjakab (the former name was Zselicszentjakab) was a village where the ordo Saint Benedict built a monastery.
The village was the place of a St Benedict monastery in the Árpád age. Some lands in the village were the private properties of the Genere Győr. In 1256 the members of the Genere Győr had given their Zselicszentjakab family monastery to Pannonhalma Archabbey. In 1328 the Genere Győr (Péter and Miklós, sons of Derzs) and the abbot of Zselicszentjakab changed back the lands of the monastery by the lands of Rábacsécsény at the Pannonhalma Archeabbey.
Today the old village is part of the county capital town Kaposvár. The Somogy County villages suffered great devastation during the Turkish wars, and Zselicszentjakab monastery was also destroyed.
The ruins of the old St Benedict Monastery was renovated and a beautiful excursion place is the old monastery district in the southeastern egde of Kaposvár. The ruins shows the ground plan of the church building and the monastery. The church had 3 naves. Architectural comparisons proved the eastern connections of the central space, with four columns. This church also belonged to the Eastern Orthodox (Caucasian, Byzantine) tradition related churches in Hungary, which were found at least at 5 churches: Tarnaszentmária, Feldebrő, Székesfehérvár, Szekszárd and here in Zselicszentjakab. Ruins of a central spaced chapel can also be found north of the monastery buildings.
