Notre Dame de Paris itself is a historical treasure.
Notre Dame de Paris is a Gothic building and one of the landmark buildings in Paris, France. Established in 1 163 and completed in 1345. It is the first Gothic church in the history of the world that integrates religion, art and culture. All kinds of altars, cloisters, doors and windows in it have high artistic value and very high historical research value. From these aspects, Notre Dame de Paris itself is a historical treasure. Even if it is destroyed and repaired, it still retains a complete general framework and has high research value. What's more, Notre Dame de Paris itself is one of the representative places of interest in France, which is world-famous and invaluable.
Second, the art of Notre Dame de Paris is more valuable.
Before the fire, Notre Dame de Paris was not only a church, but also a museum, which contained a large number of works of art from13rd century to17th century. These works of art are treasures left by major European artists at that time, which are in perfect harmony with the temperament of Notre Dame de Paris, and their value is even more inestimable. In this respect, as long as these works of art can return to Notre Dame after the restoration work is completed, Notre Dame can still continue its previous glory.
On the whole, I think Notre Dame de Paris still has its previous value after its restoration.
