How long did it take to construct the Notre-Dame Cathedral?

Considered one of the architectural wonders of the Gothic Period, The Notre-Dame de Paris, aka Notre-Dame Cathedral, was the dream of Bishop Maurice de Sully in 1160. In 1160, the Paris church was the central church for all of Europe and recognized by most kings. It took three years to demolish the Paris church and begin construction of Notre-Dame. Pope Alexander III even came to witness the laying of the cornerstone in 1163.

Construction would continue on and off, at the mercy of funds and manpower, until 1345. There are several features about the structure that set it apart from other buildings of the time period. It was one of the first buildings to utilize the “flying buttress”. These arches were designed to support walls and enable a larger roof, while allowing large sections for windows. Because of the supports, the north rose window was constructed. This window is still considered the largest at 39 feet in diameter and 123 feet circumference.

Over the centuries, Notre-Dame has been repaired and renovated, especially during the Huguenot Rebellion and the French Revolution. Excavations continue to find hidden rooms and other secrets within the structure.
