The construction of Notre Dame Cathedral is one of the most remarkable architectural achievements of the medieval era. This iconic Parisian landmark took centuries to complete, with countless artisans, engineers, and laborers contributing to its grandeur. Understanding the timeline of its construction helps appreciate the dedication and craftsmanship behind one of the world’s most famous cathedrals. Let’s explain you How long did it take to build Notre Dame cathedral.
Challenges and delays during construction
Medieval engineering limitations
Building Notre Dame in an era without modern tools and machinery was a monumental challenge. Medieval architects relied on trial and error, as well as innovative techniques like rib vaults and flying buttresses, to support the cathedral’s immense weight.
Wars and political turmoil
Throughout its construction, France experienced wars, plagues, and economic downturns, causing interruptions and slow progress. The Hundred Years’ War (1337–1453) also diverted resources away from construction projects.
The timeline of Notre Dame’s construction
When did construction begin?
The foundation stone of Notre Dame de Paris was laid in 1163 during the reign of King Louis VII. The cathedral was commissioned by Bishop Maurice de Sully, who envisioned a grand structure that would reflect Paris’s growing importance as a religious and cultural center.
Major phases of construction


- 1182-1250: This period marked the construction of the western façade, the nave, and the twin bell towers. The western façade, which houses the magnificent three portals (depicting biblical scenes such as the Last Judgment), was carefully designed to reflect the grandeur and solemnity of the cathedral. By the early 13th century, work on the rose windows began, introducing breathtaking stained glass that would become one of Notre Dame’s most defining features. The two iconic bell towers, standing at 69 meters tall, were completed around 1250, giving the cathedral its recognizable silhouette.


- 1250-1345: This phase saw the completion of the flying buttresses, which reinforced the cathedral’s stability and allowed for the construction of larger stained-glass windows, including the famous south rose window. Additional chapels were also built around the choir, adding to the cathedral’s grandeur. The sculptural decoration, including the intricate gargoyles and chimeras, was finalized, giving Notre Dame its characteristic medieval aesthetic. By 1345, the cathedral was considered complete, with its towering architecture standing as a symbol of Paris’s spiritual and cultural prominence.
By 1345, nearly two centuries after its inception, the cathedral was considered fully built, though minor additions and renovations continued in later years.


Notre Dame’s evolution over the centuries
Although officially completed in 1345, Notre Dame continued to evolve:
- 17th-18th Century: During this period, the cathedral underwent significant modifications to align with changing religious and artistic sensibilities. Many medieval decorations were removed, and baroque influences were introduced. In 1699, at the request of King Louis XIV, the original medieval choir screen was dismantled to make way for a more open and grandiose design. New baroque-style altars and chapels were added, reflecting the artistic preferences of the time. The cathedral also became the site of important royal ceremonies, further solidifying its status as a central monument of French religious and political life.


- French Revolution (1789-1799): The French Revolution brought significant devastation to Notre Dame. The cathedral, seen as a symbol of the monarchy and religious authority, was looted and severely damaged. Revolutionary forces beheaded statues of biblical kings, mistaking them for French monarchs, and many treasures, including religious artifacts, were either destroyed or stolen.
The church was officially secularized and renamed the Temple of Reason, hosting radical political events instead of religious ceremonies. The iconic bells, except for one, were melted down to create cannons, and the structure itself fell into neglect. By the end of the Revolution, Notre Dame was in a state of ruin, requiring urgent restoration.
- 19th century restoration: By the early 1800s, Notre Dame was in a dire state of disrepair. Public interest in the cathedral was reignited by Victor Hugo’s novel The Hunchback of Notre-Dame (1831), which highlighted its architectural beauty and historical importance.
This led to a widespread movement to save the structure. In 1844, King Louis-Philippe ordered an extensive restoration, led by architects Eugène Viollet-le-Duc and Jean-Baptiste Lassus. The restoration included rebuilding the spire, restoring damaged sculptures, and reinforcing the flying buttresses. Viollet-le-Duc also added new gothic elements, sometimes interpreting the medieval style rather than replicating it precisely. The project took over 20 years and was completed in 1864, ensuring Notre Dame’s survival for future generations.
