Large Magellanic Cloud (LMC) provide a interesting globular cluster population that cover a large range of age, metallicity and integrated colors. These objects can be used as good tracers of chemical evolution of LMC. Unfortunaly actually we dont possess homogeneous reliable age and metallicity scale for LMC clusters and the effective shape of age-metallicity relation (AMR) is already not clear. We present the first results from our photometric-spectroscopic survey devoted to unveil the correct AMR for LMC. Our main results are : (i) the determination of detailed chemical abundances ([Fe/H], $\alpha$-elements, Fe-peak elements...) using high-resolution UVES@FLAMES spectra and (ii) the determination of accurate age based on direct measurement of the Main Sequence Turn-Off level in high-quality Color Magnitude Diagrams for six globulars selected from our database.
