If the Notre-Dame Cathedral in Paris reopens in time for the 2024 Olympics, as President of the Republic Emmanuel Macron has pledged, the merit will also be an "Italian-made" laser. A sophisticated ray of light produced by Tuscan Deka, a subsidiary of the Italian multinational El.En, which ranks among the top five in the world in the medical laser sector. Over time, light beams have become increasingly sophisticated and adaptable to various purposes. The "Punto" laser has been utilized for just over a month in Beirut's Rizk hospital to treat the burn scars of over 7,000 people who were damaged and injured by the huge explosion in the capital's port in August 2020. However, Punto is also useful for the preservation of cultural heritage, as the laser enables damage-free cleaning of monuments. Before restoring Notre-Dame, El.En cleansed a long list of masterpieces, including frescoes in the Villa of the Mysteries in Pompeii and warriors in Xian, China, as well as the Holy Sepulchre's Door in Jerusalem and Michelangelo's statues at San Lorenzo in Florence.
