It is a shame that Notre Dame burned down in Paris. I've been there many, many times in the 70's, 80's, and the 90's while I was in the Army. Beautiful stained glass, unbelievable woodworking and spectacular architecture.That building survived 2 FN World Wars and all of the revolutions and other BS in that country for centuries. We will probably find out the fire was an accident started by the contractors working on its renovation.
