When I visited this landmark in 2013, Paris was celebrating the 850th year of Notre Dame's history. In itself, that was a stunning realization - this building has been here, being built, completed, restored - since 1163. The construction itself required 182 years - in medieval times that was essentially five lifespans!
Beyond the facts of the edifice...its impact on your senses is indelible. Soaring spaces, beautiful light, amazing glasswork; most impressive - the unique simplicity of the interior. Everything focused on the altar, and the symbolic center of the building's purpose - the celebration of faith.
Exploring this place, I found myself deeply moved - Notre Dame is truly one of humanity's greatest expressions of collective purpose and artistic achievement. A monument from the ages - for the ages.
