## Abstract We consider non‐compact WZW models at critical level (equal to the dual Coxeter number) as tensionless limits of gravitational backgrounds in string theory. Special emphasis is placed on the Euclidean black hole coset __SL__(2,__R__)~__k__~/__U__(1) when __k__ = 2. In this limit gravity
