Restoration

In 2011 Diego Della Valle, head of the shoe firm Tod's, entered into an agreement with local officials to sponsor a €25 million restoration of the Colosseum. Work was planned to begin at the end of 2011, taking up to two and a half years. Due to the controversial nature of using a public–private partnership to fund the restoration, work was delayed and began in 2013. The restoration is the first full cleaning and repair in the Colosseum's history. The first stage is to clean and restore the Colosseum's arcaded façade and replace the metal enclosures that block the ground-level arches. After three years, the work was completed on 1 July 2016, when the Italian minister of culture, Dario Franceschini, also announced that the funds have been committed to replace the floors by the end of 2018. These will provide a stage that Franceschini says will be used for "cultural events of the highest level." The project also includes creating a services center and restoring the galleries and underground spaces inside the Colosseum. Since 1 November 2017, the top two levels have been opened for guided visits. The fourth level held the marketplace, and the top fifth tier is where the poorest citizens, the plebeians, gathered and watched the show, bringing picnics for the day-long event.
