The National Garden Show 2012 in Bamberg allows for the first time, even if only temporarily, to build a place of worship for three religions. During the State Garden Show 2012, the house of prayer of religions, invited Christians, Jews and Muslims "to touch the paradise".

The project had a lifetime of about six month, from 26 April 2012 to 7 October 2012. The diameter of the base plate was about 10m, the usable floor area was 60m² and the total height of the structure was about 6,10m.
A dome of three, in the same direction curved, printed surfaces embodies the three monotheistic religions that revolve around a common center. The supporting structure of the dome is divided into a main structure and three shell structures, which supports on the base plate, and the high point of the main structure. The main structure consists of three curved, point-symmetrically arranged steel tubes which meet at the highest point on a circular ring. The three bowls are biaxial curved in the same direction, geometrically identical lattice structures and also arranged point-symmetrically around the center. Two of the dishes are executed mobile and thus provide a setting for the entrance to the place of prayer.

To stiffen the shells and as bearing system for the membrane lattice structures were provided with a network of bent steel tubes with very small diameters. This supporting structure is followed by the clamping of a printed translucent tissue consisting of extremely high tensile strength polyester fibers and a PVC coating to protect for UV radiation and other environmental influences. Due to the translucency of the fabric, the printing can also be performed inside the structure while also ensuring adequate illumination without additional light sources.
