Abstract: The Magellanic Clouds MCs present a rich system of stellar clusters thatcan be used to probe the dynamical and chemical evolution of these neighboringand interacting irregular galaxies. In particular, these stellar clusters SCspresent combinations of age and metallicity that are not found for this classof objects in the Milky Way, being therefore very useful templates to test andto calibrate integrated light simple stellar population SSP models applied tounresolved distance galaxies. On its turn, the age and metallicity for acluster can be determined spatially resolving its stars, by means of analysisof its colour-magnitude diagrams CMDs. In this work we present our method todetermine self-consistent physical parameters age, metallicity, distancemodulus and reddening for a stellar cluster, from CMDs modelling of relativelyunstudied SCs in the Small Magellanic Cloud SMC imaged in the BVI filterswith the 4.1 m SOAR telescope. Our preliminary results confirm our expectationsthat come from a previous integrated spectra and colour analysis: at least oneof them Lindsay 2 is an intermediate-age stellar cluster with ~ 2.6 Gyr andFe-H ~ -1.3, being therefore a new interesting witness regarding thereactivation of the star formation in the MCs in the last 4 Gyr.
