The design choices adopted by Cobar in the monumental complex of Barberini Palace were the result of a joint analysis between the structural design, the architectural design and the engineering needs, and were mediated by a careful reading of all terms, conditions and constraints.

The analysis has highlighted the need to proceed on the planning of different interventions:

– The consolidation of the vaulted orientations through a traditional system of steel chain insertion, aimed at eliminating horizontal thrusts on the wall mast;

– The optimization of the vertical distribution system through the installation of three new elevator systems, eliminating overlappings and stackings due to the fractioning of the building;

– The improvement of the bottom soils in an area with a significant differential erosion;

– The insertion of air conditioning systems, the adaptation of electrical and lighting systems and special hi-tech systems (anti-intrusion, sound diffusion, monitoring and control);

– The creation of a control room from which all systems can be managed, thus providing the complex with the latest technologies capable of bringing the museum up to modern international standards.

Subsequent intervention instances focused on the recovery of the building’s surfaces.

The following areas have been restored: the porticos, the garden access ramp, the greenhouse and its perimeter wall, the vault’s cornices and the wainscoting of some rooms on the ground floor and the main floor, the square staircase, all the stone portals and the fireplace of the Salone by Pietro da Cortona, the oval room, the atriums and the decorations of all other rooms on the ground floor and the main floor.
