A beautiful church on top of a hill in Paris
Sacre Coeur is an incredibly beautiful Church sitting atop Montemarte, a large hill in Paris. From the top of the hill, you'll have a great view of the City and horizon. Montemarte is also conveniently located within walking distance of the Moulin Rouge so that you can see several points of interest on your trip.
Be sure to go inside Sacre Coeur as it is arguably even more beautiful inside than it is on the outside with a large Jesus looking upon you as you enter the Church.
As you walk up the hill to the Church, you will likely be approached by hagglers (there can be many, too) but if you ignore them, you are in no danger. Locals also come to this spot to drink wine and watch the sunset from the top of the hill.
