Did you know that there was a wax museum in the center of Paris? Musée Grevin was founded in 1882 and now contains some 300 characters arranged in scenes from the history of France and modern life. Its baroque architecture includes a mirrored mirage room based on the principle of a catoptric cistula and a theater for magic shows.
It has an ornate main entrance on Boulevard Montmartre and another entrance in Passage Jouffroy.
Hummmm.... you scratch my back and I'll scratch yours?
10, boulevard Montmartre
