Off course I like Eiffel Tower and Notre Dame, but my favourite sights of Paris are Sacre Coeur and Sainte Chapelle.
I took these shots with my phone in the summer of 2015. The Basilica of the Sacred Heart of Paris, commonly known as simply Sacre Coeur is a Roman Catholic church.
You get the most beautiful panoramic views of Paris from the top - just breathtaking! (fourth picture).
