Abstract
The phase diagram of 2d Lorentzian quantum gravity (LQG) coupled to conformal matter is studied. A phase transition is observed at () which can be thought of as the analogue of the barrier of Euclidean quantum gravity (EQG). The non--trivial properties of the quantum geometry are discussed.
