The hamlet of Črdenc is a contraction of Črni studenec 'black spring', referring to the source of Black Creek (). History Roman-era graves have been found in Dol pri Hrastniku, testifying to ancient settlement in the area. Part of a Roman sacrificial altar was discovered during roadwork and is now built into the rectory wall next to the entrance. During the feudal era, the village consisted of nine full farms and three smaller farms. During the Second World War, there was Partisan activity in the area from 1941 onward. In early March 1945, a Partisan unit attacked a German base at the school, resulting in the surrender of 100 German troops that then joined an Austrian partisan unit. After the Second World War, a new mining operation was established in the hamlet of Novi Dol, resulting in construction that made many of the hamlets contiguous.
