SFORZESCO CASTLE: main façade and tower

We needed to make perforations in the building's floor, and it took considerable time and arguments to establish a credible reason for it. Our research led us to establish the structural system used for the renovation and to determine how we could use it to pierce the holes in a manner that meets our expectations and complies with museum protocols. These perforations served to support the lighting fixtures and lower them to the ground level for relamping, similar to the theatre. This system has been in place for 25 years.
