Metz Cathedral (Cathédrale Saint-Étienne de Metz)

The Saint-Étienne Cathedral in Metz took 300 years to build. The result is an impressive bishop's church, which is one of the most beautiful and largest Gothic church buildings in France.
I'll tell you why it's also called the "Lantern of God" in my blog post: netreisetagebuch.de/metz-sehenswuerddigen

The Saint-Étienne Cathedral (German: St. Stephen's Cathedral) in Metz in Lorraine was built between 1220 and 1520 and is considered one of the most beautiful and largest Gothic church buildings in France. With a vault height of more than 41 meters, it has the third highest interior after the cathedrals of Amiens and Beauvais; the area of its stained glass is around 6,500 m², the largest in a French cathedral, hence the name La lanterne du Bon Dieu - English: "The Lantern of the Good Lord". It is therefore also one of the masterpieces of the Gothique Rayonnant. It is the episcopal church of the diocese of Metz. Since 1930, the cathedral has been classified as a monument historique (cultural monument) and protected (Wikipedia).
