The Colon Theatre Restoration Plan is a comprehensive project for renovation and technological restoration development to reserve the building’s original architectural style and preserve its acoustic quality, which is a characteristic that distinguishes this theatre as the best opera house in the entire world. The Main Room, the Golden Room, the Foyer and the Chariot Hall were completely refurbished. The existing rehearsal rooms were restored and a new one was opened for opera performance. The building´s technical infrastructure and stage technology were totally restored. The stage with its revolving area, the anti-ignition curtain and the pit were readjusted. The workshops, staging areas and warehouses were re-organized.
