[Editor's Note: On 15 April, 2019, a fire destroyed large portions of Notre-Dame. The much of the historic wooden roof and the cathedral spire were lost. As of this edit, the extent of the damage was still being assessed. The cathedral will be forced to close for the foreseeable future.] Cathédrale Notre-Dame de Paris, known simply as Notre-Dame, is often described as the very heart of Paris. Construction work began in 1160 and was largely completed in 1260, through renovations and modifications occurred often over the following centuries. It is a stunning example of French Gothic architecture and particularly well-known for its many gargoyles and flying buttresses. The cathedral’s stained glasses windows date from the 13th century, making them essentially priceless. Notre-Dame has played an important role throughout French history. In 1802, Napoleon Bonaparte was crowned Emperor of France here. Located on the Ile de la Cite in the Sine River, Notre-Dame is a true masterpiece.
