We introduce a new invariant, Pontrjagin-Viro form, of real algebraic surfaces. We evaluate it for real Enriques surfaces with non-negative minimal Euler characteristics of the components of the real part and prove that, when combined with the known topological invariants, it distinguishes the deformation type of such a surface.
