Spectacular Gothic architecture. Gargoyles. Stained glass to die for. The Notre Dame cathedral in Paris lives up to everything you've ever read about it. Dating back to the 1100s, this is a really, really old church. It's been restored at various times over the centuries and today it remains it good shape. At least as far as the monkey could tell. Kongo didn't climb the belfry but might be tempted to do it at some later date when he had more time.
Travel safe. Have fun.
