We have searched the WFPC2/HST archive for data on nearby massive young clusters with low extinction and we have analyzed 27 such objects. A clear dichotomy between objects with a compact core and without it is observed. We attribute this bimodality to the initial conditions of the parent giant molecular clouds and we discuss its implication towards the long-term evolution of the clusters.
