One one of our days in Paris, we visited both the Sacre Coeur and Moulin Rouge.
The Sacre Coeur is also known as The Basilica of the Sacred Heart of Paris. It is a roman catholic church dedicated to the sacred heart of Jesus. It was consecreated in 1919 and is constructed in the ancient Roman and Byzantine architecture. This church sits on the top of the hill of Montmartre, and, from its stairs, you can see amazing views of the city as it is also the 2nd highest point in the city,
The Moulin Rouge is a cabaret in Paris and is well known around the world (probably made even more famous buy various songs). I just drove past so i did not get to see the inside.
