We describe string-theory and d = 11 supergravity solutions involving symmetric spaces of constant negative curvature. Many examples of non-supersymmetric string compactifications on hyperbolic spaces Hr of finite volume are given in terms of suitable cosets of the form H-t/Gamma where is a discrete group. We describe in some detail the cases of the non-compact hyperbolic spaces F-2 and F-3, representing the fundamental regions of H-2 and H-3 under SL(2, Z) and the Picard group, respectively. By writing AdS as a U(1) fibration, we obtain new solutions where AdS(2p+1) gets untwisted by T-duality to R x SU(p, 1)/(SU(p) x U(1)). Solutions with time-dependent dilaton field are also constructed by starting with a solution with NS5-brane flux over H-3. A new class of non-supersymmetric conformal field theories can be defined via holography. (EN)
