Out of the well-known 1000-year-old reservoir, comes a meeting center. The peaceful cooperation of religions is the core of the exhibit. Ebru, the marbleized paper, is a symbol of various influences that together paint a harmonious picture. The language of shape echoes in the architecture of the new building and again in the roof of the reservoir. Forum, exhibit and café flow together in a garden on the roof of the building, from which one has an overview of Istanbul.
