Based on CCD images obtained in the Washington system at Cerro Tololo Inter-American Observatory, we determine ages and metallicities of 8 unstudied star clusters of the Large Magellanic Cloud (LMC). We find that they are intermediate-age (1-2 Gyr) and relatively metal-poor, although the metallicities are mainly determined from isochrones and are not strongly constrained. The study of this cluster sample will soon be extended to almost a hundred practically unstudied LMC star clusters.
