The challenge: the historic Palazzo Madama in Turin, one of the most representative buildings of Piedmont, a UNESCO World Heritage Site and home to the Museo Civico di Arte Antica, was opening a new public entrance for the first time.

For the occasion of a major exhibition, for reasons of safety and security, the doors had to close automatically: the constraint set by the architect Diego Giachello was not to intervene on the marble floor and not to add visible features.

The request was therefore for a very easy system to install, even in difficult situations, such as the case of a renovation under the watchful eyes of the heritage authorities.


After evaluating several solutions, the architecture studio Officina delle Idee selected the patented invisible FritsJurgens system, the only one that does not require the inclusion of architectural devices in the floor and ceiling.

The special FritsJurgens mechanism, totally built into the door, allows for two-way opening and automatic closing of the splendid 19th-century windows, with a width of about 5 meters.

The maximum load of the mechanism, 200 kg, made it unnecessary to install elements on the floor, supporting the historic doors of Palazzo Madama with their fine, heavy materials. The use of the System4 hinges by FritsJurgens, and the experience of Carlos Chiesa of Falegnameria La Quercia, have made it possible to install the whole project at the site, complying with local heritage regulations.
