Trebanjski Vrh is the site of a mass grave from the period immediately after the Second World War. The Roje Cave 1 Mass Grave (Slovene: Grobišče Rojska jama 1) is located along the road between Roje pri Čatežu and Čatež. It is a 10-meter (33 ft) deep shaft containing the remains of about 10 Slovenes from the vicinity of Roje pri Čatežu. The Yugoslav secret police (OZNA) arrested them in the first few months after the war and murdered them in the cave.[3]
