I will explain the relation between the Euclidean path integral over near-extremal black hole geometries and its dimensional reduction to 2D Jackiw-Teitelboim gravity. I will focus mostly on the case of 3D gravity and a particular application to pure 3D gravity. I will also mention a connection between more general 2D dilaton-gravity theories, matrix integrals and the minimal string.
