Parcul Carol I
After the Communist regime was established, Frimu gained official status as a hero of the labor movement in Romania, and he was claimed a precursor. His remains were transferred to the Carol Park Mausoleum, designed for prominent socialists and communists, buried in the semicircle around the monument. The Sinaia Plants were given his name, as were a number of streets in Romania's main cities and a neighborhood in Galați. In 1991, when the mausoleum was deprecated, Frimu's remains were moved to Sfânta Vineri Cemetery, Grivița.
