Located next to the civil cemetery and the church of St. Peter at Grgar is also a military cemetery. Buried in it are the Austro-Hungarian soldiers and officers who fell in World War I in the area between Plave and Sveta Gora. Initially, the fallen soldiers were buried in the civil part of the cemetery, but due to a great number of military burials the cemetery was enlarged during the war, and added to it was a separate military part. According to the data of Italian authorities that organized exhumation of soldiers from military cemeteries in the 1930s, 1,371 soldiers are buried here.
At the entrance to the cemetery there is a collective monument with the inscription “Das Vaterland seinen Helden” (To Our Heroes from the Fatherland). After the rearrangement of the cemetery in 1979, individual grave crosses were transferred and fixed to the supporting wall of the access road. The remaining restored headstones were left on their original locations.
The military cemetery Grgar lies next to the civil cemetery at the northern fringe of the village of Grgar. The easiest access to the cemetery is to go from Nova Gorica towards Grgar. When you reach Grgar, follow the signposts for Bitež. On reaching the fringe of the village, you see on the right a civil cemetery with the church of St. Peter, in front of which is a small grass area with the military cemetery.
