Cathedral of Our Lady of Strasbourg

Timeline

1. 1015

   Romanesque Cathedral construction begins

   Bishop Werner I laid the foundation stone on the ruins of the Carolingian basilica, beginning construction of a Romanesque-style cathedral, the direct predecessor of the present building.

2. 1176

   Great nave fire

   The wooden roof of the Romanesque cathedral's nave caught fire, prompting Bishop Heinrich to commission a fresh reconstruction that opened the way for a Gothic-scale rebuild.

3. 1225

   Shift to Gothic style

   A design team from Chartres was invited to Strasbourg, and the ongoing construction plan was substantially redrawn into the new high Gothic Rayonnant idiom.

4. 1277

   Steinbach family takes the lead

   Erwin von Steinbach was appointed chief architect, designing the west facade and its sculptural program; three generations of his family then carried the project forward.

5. 1439

   142m single tower completed

   Johannes Hültz completed the octagonal spire; the planned southern tower was never built, leaving the cathedral with its main structure finished in striking asymmetrical form.

6. 1524

   Cathedral turns Protestant

   During the Reformation, the Strasbourg city council voted to place the cathedral in Protestant hands, and a number of medieval sculptures were removed during the transition.

7. 1539

   Europe's first Christmas tree

   The earliest documented Christmas tree in Europe was set up inside this cathedral, marking the symbolic beginning of the modern Christmas market tradition that still gathers crowds today.

8. 1647

   World's tallest building

   After the spire of St. Mary's Church in Stralsund burned down, the 142-metre spire of Strasbourg Cathedral became the world's tallest building, a status it maintained for the next 227 years.

9. 1681

   French annexation, Catholic return

   Louis XIV annexed Strasbourg, the cathedral was returned to Catholic worship, and interior renovations in Counter-Reformation style were carried out under the new royal regime.

10. 1794

    Spire saved from demolition

    The radical Enragés faction proposed dismantling the spire in the name of egalitarianism, but Strasbourg's citizens saved it by crowning the summit with a giant tin Phrygian cap.

11. 1874

    Yielding the title of world's tallest

    Surpassed by the completed spire of St. Nikolai Church in Hamburg, though Strasbourg Cathedral remains the tallest fully medieval structure still standing today.

12. 1944

    Wartime bombing damage

    On August 11 the cathedral was damaged during an Allied air raid on the centre of Strasbourg, with restoration of the wartime injuries continuing into the early 1990s.

13. 1988

    UNESCO World Heritage inscription

    Inscribed on the UNESCO World Heritage List together with the historic old town "Grande Île," confirming its international recognition as a masterpiece of Gothic architecture.

Detailed History

The predecessor of the Cathedral of Our Lady of Strasbourg dates back to about 550-575, when Bishop Saint Arbogast erected the first cathedral on the present site. Around 778, Bishop Remi of the Carolingian era consecrated an altar and established an underground crypt, and in 842 the famous "Oaths of Strasbourg" were sworn here by Charles the Bald, king of the West Franks, and Louis the German, king of the East Franks. After the Carolingian basilica was destroyed by fire during a civil war in 1002, Bishop Werner I laid a new foundation stone in 1015 and launched reconstruction in the Romanesque style. When the wooden roof of the nave burned again in 1176, Bishop Heinrich von Hasenburg resolved to build a structure surpassing Basel Cathedral. In 1225, a team of architects from the Chartres school was invited, preserving the existing Romanesque substructure while shifting the design above to Gothic. From 1253, funding was secured through the issuance of indulgences to retain master architects and stonemasons. In 1277, Erwin von Steinbach became chief architect, overseeing the design and sculptural program of the west facade; after his death in 1318, his son Johannes and grandson Gerlach carried on the family's work. In the late 14th century, Ulrich Ensingen erected the square base of the north tower, and between 1419 and 1439, Johannes Hültz completed the octagonal spire above it. The originally planned south tower was never built due to financial constraints, leaving the cathedral with its distinctive asymmetrical silhouette. In 1524, the city council voted to hand the cathedral over to the Protestant Reformation; when Louis XIV annexed Strasbourg in 1681, it was restored to Catholic worship and the interior was reworked in Counter-Reformation style. During the revolutionary upheaval of 1794, the radical Enragés faction proposed dismantling the spire in the name of egalitarianism, but the townspeople saved it by capping the summit with an enormous tin Phrygian cap, the revolutionary symbol of liberty. The cathedral suffered damage from Prussian artillery in 1870 and from an Allied air raid on August 11, 1944, with restoration completed by the early 1990s. In 1988, the cathedral was inscribed on the UNESCO World Heritage List together with the historic old town of Strasbourg, the "Grande Île."

Cultural Significance

The Cathedral of Our Lady of Strasbourg was inscribed on the UNESCO World Heritage List in 1988 together with the historic old town "Grande Île," and stands as the emblematic religious monument of Alsace. Known as Liebfrauenmünster in German and Cathédrale Notre-Dame in French, it carries two cultural identities within a single grand structure, mirroring the dual heritage of the region itself. Victor Hugo called it "a gigantic and delicate marvel," and Goethe praised it in his essay On German Architecture as "a sublimely towering, wide-spreading tree of God," a passage credited with rekindling appreciation for Gothic architecture across Europe in the late 18th century. In 1539, the earliest documented Christmas tree in Europe was set up inside the cathedral, and the surrounding Christmas market is still celebrated as one of the oldest on the continent. During World War II, General Philippe Leclerc of the Free French Forces made the famed "Oath of Kufra," vowing not to lay down arms until the French tricolour once more flew over Strasbourg Cathedral, making the building a powerful spiritual symbol of the liberation of Alsace.

Architectural Details

Stretching 112 metres in length, with a central nave 32 metres tall internally, a west facade 51.5 metres wide, and a single tower reaching 142 metres at its summit, the Cathedral of Our Lady of Strasbourg is a masterpiece of medieval engineering. Its building material is the distinctive pink sandstone of the Vosges Mountains, which gives the cathedral its distinctive pink exterior. The structure layers Romanesque foundations beneath Rayonnant Gothic upper works, so thick Romanesque walls survive in the eastern choir and southern portal while the west facade and clerestory bristle with intricate Gothic tracery. Set at the heart of the west front is a rose window 13.6 metres in diameter, and the three-tiered sculptural program depicts the Last Judgment, scenes from the Old and New Testaments, and ranks of saints. The northern tower is a two-stage composition: a square base built between 1399 and 1419 by Ulrich Ensingen, and an octagonal spire raised from 1419 to 1439 by Johannes Hültz, using exceptionally advanced pre-drawn plans for the era and a stonework technique so precise that the masonry appears almost seamless. The interior stained glass windows span from the late 12th century to the 20th century, with notable examples including the "Imperial Windows" of the north nave and Max Ingrand's modern "Strasbourg Madonna" donated by the Council of Europe in 1956.
