With its gleaming white roof, the Church of the Blessed Father Rupert Mayer has become a new landmark in Poing, a municipality some 20 km east of Munich. The sculptural form of the roof is set on top of a storey-height plinth of conglomerate stone from the Munich gravel plain. Seen on plan, the roof is divided into four sections which are borne by a steel structure. The homogeneous outer skin of this crowning element, consisting of roughly 15,000 ceramic tiles with distinct profiles, lends the roof a crystalline appearance.
