Notre Dame

On Monday April 15th, the famous Notre Dame Cathedral in Paris, France caught on fire. This was a very tragic event that has been devastating to citizens and people around the world. Luckily, the church was evacuated before the fire so no one was hurt. (This was because of a mass that had happened prior to the event). Yesterday, President Macron said that they were starting to raise funds to rebuild it. So far, they know that that the fire began in the roof, and then spread to the spire.  Now, the fire has been extinguished, but not leaving much of it left. Now we ask the question, what caused it?
