               Based on CCD images obtained in the Washington system atCerro Tololo Inter-American Observatory, we determine ages and metal-licities 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 isochronesand are not strongly constrained. The study of this cluster sample willsoon be extended to almost a hundred practically unstudied LMC starclusters.
