The church of Santa Anna in Duren is built on the remains of a ruined during World War II church. The project, in the early 50s, preserved at the entrance what remained of the church, while the rest is a new building where a simple concrete structure, wisely uses a usual slightly brownstone in the area, and above all, a natural light that bathes the entire central nave.

The cross section of the church helps to see the illuminated ship without perceiving the light source, and the path to go through a single aisle, can understand the space directly undiscovered secrets.
