Projective invariance is a symmetry of the Einstein-Hilbert action and of minimally coupled matter fields. It is also intimately related to the reparametrization invariance of geodesics. I will discuss the relevance of this symmetry for the physical interpretation of the Schwarzschild solution and for the classification of curvature singularities. [Speaker: Gonzalo J. Olmo]
