Diocese of Sarsenterum (Latin: Dioecesis Sarsenterensis) was a Latin Roman Catholic diocese in the area of present Bosnia and Herzegovina, restored as a titular see by Pope Benedict XVI in 2009.
The Diocese of Sarsenterum was established during the Second Church Synod in Salona in 533 presided by Archbishop Honorius II.
The Diocese was given the basilicas from the municipal areas of Dellontino, Stantino, Nouense (Neuense) per Rusticiarum, Potuatico, Beuzavatico (Benzavatico) and others as well.
[3] Since no epigraphic inscription has been found to localize Sarsenterum, there are different theories about the location of this settlement.
[4] Relying on the ancient Church provision that dioceses can only be founded in cities worthy of a bishop's dignity, some contemporary archaeologists and historians located in the area of Stolac where the most important urban center in that part of the province of Dalmatia developed.
