heal.abstract	The phase diagram of 2d Lorentzian quantum gravity (LQG) coupled to conformalmatter is studied. A phase transition is observed at $c=c_{\rm crit}$($1/2<c_{\rm crit}<4$) which can be thought of as the analogue of the $c=1$barrier of Euclidean quantum gravity (EQG). The non--trivial properties of thequantum geometry are discussed.	en
