Notre-Dame Cathedral is an iconic of Paris. Completed in the 14th century, it has been the site of numerous historical events, including the coronation of Napoleon and the beatification of Joan of Arc. Despite being severely damaged by fire in 2019, Notre-Dame remains a must-visit for its cultural and spiritual significance. Restoration efforts are ongoing.

Notre-Dame is worth visiting for purely geographical reasons. It's located in one of the most beautiful parts of the city. Take a stroll down the Seine when you're done.
