Description	Using reflection groups of the Picard lattice, and (sometime) unique reconstruction of Bott-Samelson varieties, one can characterize total flag varieties of semisimple algebraic groups in terms of their elementary contractions. This implies their rigidity in families of Fano manifolds. The talk is based on a joint projects with Munoz, Occhetta, Sola Conde, Watanabe and Weber.
