At the international gravesite, which lies against the Russian gravesite, there rests those who died when the prisoner transport ship "Riegel" was sunk in 1944. This German ship was travelling southbound with 2-3,000 prisoners who were being transported to concentration camps in Germany - those aboard were mainly Russians, Yugoslavians and Poles, along with a few hundred Germans and nine Norwegians. The Riegel was sunk by an English military aircraft in a narrow sound between Tjøtta and the island Rosøya. Twenty-five years later, it was decided that the deceased be exhumed and buried at Tjøtta.

The international gravesite is shaped like a grove - the graves are located in a recessed oval rotunda - similar to an old ship grave.
