The metallicities of 15 Small Magellanic Cloud (SMC) clusters are determined from the Calcium ii-triplet lines in spectra obtained using the FORS2 multi-object spectrograph on the VLT (Paranal, Chile). The metallicity distribution, metallicity gradient and age-metallicity relationship in the SMC are determined and analyzed using new and literature data for these and other, previously studied SMC objects. Only the main results regarding these topics are presented and discussed.
