Within four dimensional (4d) N=1 supergravity theories we present extreme dilatonic domain wall solutions with a general overall coupling α in the dilaton K" ahler potential. We concentrate on extreme Type I walls, which are static, planar configurations, interpolating between Minkowski space-time and a new type of space-time with a varying dilaton field. α=0 case yields extreme ``ordinary'' supergravity walls between Minkowski and anti-de Sitter space-times. For α=1 the walls are extreme ``stringy dilatonic'' walls of the three level superstring vacua interpolating between the constant and linear dilaton vacuum. Extreme stringy dilatonic walls (α=1) serve as a dividing line between the walls (0<α<1) with the (planar) singularity covered by the horizon and those (α>1) with the naked singularity. Striking similarities between the global space-time structure of such domain walls and and the one of the corresponding extreme charged black holes with a general dilaton coupling are pointed out.
