  Constant curvature black holes are constructed by identifying points in
anti-de Sitter space. In n dimensions, the resulting topology is R^{n-1} * S_1,
as opposed to the usual R^2 * S_{n-2} Schwarzschild black hole, and the
corresponding causal structure is displayed by a (n-1)-dimensional picture, as
opposed to the usual 2-dimensional Kruskal diagram. The five dimensional case,
which can be embedded in a Chern-Simons supergravity theory, is analyzed in
detail.
