After five years and a cost of 700 million euros, the restoration project of Notre Dame de Paris is coming to an end. After the fire in 2019, the reconstruction of this Gothic building was full of challenges. However, the intervention of modern technology allowed it to be reborn. The application of artificial intelligence, 3D modeling, digital twins and other technologies not only ensures the accuracy and efficiency of reconstruction work, but also demonstrates the huge potential of technology in the field of cultural relics protection. During the restoration work, traditional craftsmanship and modern technology were perfectly integrated. 2,400 oak trees were rebuilt on the roof, and more than 2,000 sculptures and decorations were carefully restored. Laser scanning technology ensured that the reconstruction accuracy reached 1-2 mm.
After a five-year restoration project, this Gothic architectural masterpiece built in the 12th century is about to reopen to the world. The fire that shocked the world in 2019 not only destroyed the iconic spire of Notre Dame de Paris, but also caused heavy damage to this ancient building that carries the memory of human civilization. However, with the help of modern technology, this historical building is returning to the world with a completely new look.
This massive project, which cost approximately 700 million euros (approximately 5.3 billion yuan), mobilized more than 250 companies and more than 2,000 craftsmen to participate. Most notably, modern technology played a key role in this restoration project. The application of artificial intelligence and 3D modeling technology makes the reconstruction of this ancient building more accurate and efficient.
One of the technical highlights of the reconstruction project is the use of digital twin technology. The well-known design software company Autodesk was invited to develop a digital model of Notre Dame de Paris. With the support of modern Building Information Modeling (BIM) software and cloud computing technology, the team completed an accurate modeling work involving 12,000 objects, more than 30,000 square meters of stone walls, more than 3,900 square meters of lead roofs, and 186 church vaults. .
More importantly, the design company Art Graphique et Patrimoine (AGP) completed a detailed digital scan of the church's internal structure before the fire. These precious data provide important reference for reconstruction work. The restoration team used laser scanning technology to collect hundreds of thousands of data points per second with an accuracy of 1-2 mm, ensuring the accuracy of the reconstruction work.
The entire restoration project is a perfect fusion of traditional craftsmanship and modern technology. The restoration team used 2,400 oak trees to rebuild the roof, and also carefully restored more than 2,000 sculptures and decorative objects. Through 3D modeling technology, engineers can not only evaluate the stability of the building structure, but also simulate different lighting schemes and optimize the layout of construction equipment.
On November 8, the bells of the North Bell Tower of Notre Dame Cathedral resounded over Paris again, symbolizing the rebirth of this ancient building. Today, the interior nave of the church has been completely renovated, with seats and liturgical furniture neatly arranged, and the iconic rose window restored to its former glory.
Notre Dame de Paris will officially open to the public on December 7-8. This building, which combines ancient craftsmanship with cutting-edge technology, will continue to bear witness to the inheritance and development of human civilization with a new look. This restoration project not only demonstrates the important value of modern technology in the protection of cultural relics, but also provides valuable experience for the restoration of other ancient buildings around the world.
The restoration of Notre Dame de Paris is an example of the perfect integration of traditional skills and modern technology. It also provides valuable experience and reference for the restoration of ancient buildings around the world. Its rebirth is not only the recovery of a building, but also the continuation and inheritance of human civilization.
