Abstract
The spatial distribution of sources populating different regions of the col our-magnitude diagram (I - J, I) extracted from the DENIS catalogue towards the Magellanic Clouds (DCMC - Cioni et al. 2000) reveal significantly diff erent morphologies. Each region is associated to a different age group. The Large Magellanic Cloud (LMC) shows an extended circular shape with a promi nent, off center bar, a nucleus and irregular spiral arms. The Small Magell anic Cloud shows a perturbated structure with a prominent central concentra tion of stars. Old and young populations are offset from one another.
