I will be giving a pedagogical introduction to the BTZ black hole solutions in three-dimensional gravity, and propose a new way of describing their entropy via the Turaev-Viro state sum model. This will be the occasion of introducing the Turaev-Viro model (which is the only well-defined spin foam model that exists so far), to explain in which sense it can be seen as the quantization of three-dimensional gravity, and how it can be used to compute topological invariants and describe observables.
