We consider 4D SU(N) gauge theories coupled to gravity in the Causal Dynamical Triangulations (CDT) approach, focusing on the topological classification of the gauge path-integral over fixed triangulations. We discretize the topological charge and, after checking the emergence of topology and the continuum scaling on flat triangulations, we show that topology emerges on thermalized triangulations only in the so-called C-phase of CDT, thus enforcing the link between such phase and semi-classical space-time. We also provide a tool to visualize the topological structures.
