The remains of the Monastery of St. Peter de Campo are situated on the edge of Dižvar field and to the South of the village of Bihovo, near Trebinje. The complex consisted of two churches dedicated to St. Peter (rebuilt in 1906) and St. Paul (remains), monastery walls and a necropolis (stećci). Not much is known regarding the time, in which this monastery was erected. The Bishopric of Trebinje is first mentioned in a letter of Pope Benedict VIII (1012-1024) in 1022, which indicates that the monastery was erected prior to this date. In the "Letopis popa Dukljanina" it is stated that Radoslav, the brother of the Dioclean ruler Mihailo Vojisavljević (reigned ca. 1046-1081), was buried here. Mavro Orbini reports that the Grand Župan Desa of Raška (reigned 1144-1165) was buried in the Church of St. Paul within this monastery complex.
