N2 - We consider higher dimensional generalizations of the four dimensional topological Taub-NUT-AdS solutions, where the angular spheres (θ,φ) are replaced by planes and hyperboloids. The thermodynamics of these configurations is discussed to some extent. The results we find suggest that the entropy/area relation is always violated in the presence of a NUT charge. We argue also that the conjectured AdS/CFT correspondence may teach us something about the physics in spacetimes containing closed timelike curves. To this aim, we use the observation that the boundary metric of a (D + 1)-dimensional Taub-NUT-AdS solution provides a D-dimensional generalization of the known Gödel-type spacetimes.
