On Monday, 15 April the world waked up on one of the worst news ever. The fire of Notre Dame cathedral in Paris that happened at 7:00 PM local time. A catastrophic fire raised on Monday demolishing the 850-year iconic spire and roof of the cathedral, just a few days before the Easter. Both front towers are safe now despite the doubts that north tower could be saved. Fortunately, the copper statues that used to be on the collapsed spire were removed on 11 April due to maintenance purpose.
