Basilica of Saint-Denis

The Basilica of Saint-Denis (French: basilique royale Saint-Denis; now formally known as the basilique cathédrale Saint-Denis) is a Roman Catholic cathedral that originated as a medieval abbey church. It is located in the commune of Saint-Denis, a northern suburb of Paris, France. The building is of singular importance historically and architecturally because its choir, completed in 1144, is widely considered the first structure to employ all of the elements of Gothic architecture.
