Together with the redesign of the Stauffacher, the exterior lighting of the St. Jakob church was renewed. The lighting of the entrance facade and the tower are important elements to give the Stauffacher an adequate identity and space in the evening. This integrates the church forecourt into the public space, while the tower - visible from afar - serves as an orientation.

The St. Jakob church was built in 1901 by the architects Johannes Vollmer and Heinrich Jassoy in the Neo-Renaissance style. The light projection process allows a precise modulation of the building to be achieved. The architecture is drawn in its characteristics, which are based on the appearance at the time of origin.
