  We study the local behaviour of static solutions of a general 1+1 dimensional
dilaton gravity theory coupled to scalar fields and Abelian gauge fields near
horizons. This type of model includes in particular reductions of higher
dimensional theories invariant under a sufficiently large isometry group. The
solution near the horizon can in general be obtained solving a system of
integral equations or in favourable cases in the form of a convergent series in
the dilaton field.
