About
Aachen Cathedral stands as an enduring monument of Western Christian civilization and the oldest cathedral structure in Northern Europe. Commissioned by Emperor Charlemagne in the late eighth century as his imperial Palatine Chapel, it bridged Roman architectural majesty with the theological vision of the Heavenly Jerusalem.
Within the broader Abrahamic temple tradition, the cathedral represents a physical axis where heaven and earth converge under divine covenant. Rooted in biblical archetypes of sacred space, the sanctuary was designed to reflect cosmic order, sacred geometry, and the divine call to communal righteousness through Christ.
For over six centuries between 936 and 1531, this sacred precinct served as the coronation church for thirty-one German kings and twelve queens consort. In 1978, its architectural ingenuity and spiritual significance earned it status as the first German site inscribed on the UNESCO World Heritage List.

The Wartime Guardians on the Cathedral Roof
1944
During the devastating aerial bombings of 1944 that leveled most of surrounding Aachen, the ancient Carolingian cathedral was saved by extraordinary personal heroism. Master mason Joseph Buchkremer organized teams of volunteers and students who stationed themselves atop the wooden rafters during intense air raids. Working through smoke and fire, they threw burning incendiary bombs off the roof trusses before the timbers could ignite.

MilestoneHistory by Decade
790s — Carolingian Foundation
He built the most beautiful basilica at Aachen, adorning it with gold and silver, candelabra, and choir screens.
Charlemagne selected the Roman thermal settlement of Aachen to establish his permanent winter palace and administrative capital. Master builder Odo of Metz supervised the erection of the octagonal chapel using advanced stone vaulting techniques. Antique marble columns and capitals were hauled across the Alps from Rome and Ravenna to invest the Frankish kingdom with Roman imperial gravitas.
800s–880s — Imperial Consecration and Raids
Following Charlemagne's imperial coronation in Rome, Pope Leo III traveled north to consecrate the Palatine Chapel in 805. The emperor's death in 814 permanently anchored the church as a sacred imperial mausoleum. In 881, Viking raiders attacked the palace and stabled horses inside the chapel, but the robust stone vaulting resisted destruction.
930s–1020s — The Coronation Church
Otto I selected the cathedral in 936 as the setting for his coronation, establishing Aachen as the mandatory royal coronation church of Germany. Ottonian emperors enriched the interior with spectacular artistic commissions, including the golden Pala d'Oro altar and the Ambo of Henry II. Emperor Otto III opened Charlemagne's tomb in 1000 before being buried himself beneath the choir.
1160s–1230s — Imperial Shrines and Golden Age
Emperor Frederick Barbarossa promoted the veneration of Charlemagne, installing the grand Barbarossa Chandelier to represent the celestial Jerusalem. Frederick II completed the intricate Karlsschrein in 1215 to encase the monarch's bones in gilded silver. Shortly thereafter, the Marienschrein was crafted to house the four great relics of Christ and the Virgin Mary.
1350s–1420s — Building the Gothic Glass House
Overwhelming throngs of international pilgrims prompted the cathedral chapter to lay the cornerstone for a vast Gothic eastern choir in 1355. Consecrated in 1414, this soaring choir featured thirteen lancet windows rising over twenty-five meters high. Known as the Aachen Glass House, its daring structural design minimized stone walls to maximize heavenly light.
1530s–1790s — End of Coronations and Baroque Renewal
The coronation of Ferdinand I in 1531 marked the thirty-first and final royal crowning in Aachen before ceremonies moved to Frankfurt. Catastrophic fire in 1656 damaged the roofs, leading to the construction of the distinctive baroque lantern cupola over the Octagon. In 1794, occupying French Revolutionary troops secularized the chapter and carried antique columns off to Paris.
1800s–1930s — Prussian Restoration and World War
Aachen was elevated to a permanent episcopal see, prompting comprehensive restorations overseen by the Karlsverein after looted columns were repatriated. Neo-Byzantine mosaics were installed across the octagonal dome between 1880 and 1901 to revive the lost medieval decorative scheme. Pope Pius XI definitively re-established the modern Diocese of Aachen in 1930.
1940s–2020s — Reconstruction and World Heritage
Allied bombing raids heavily damaged the Gothic choir glass during World War II, but the core vaults survived through the efforts of volunteer fire brigades. Postwar restoration culminated in Aachen Cathedral becoming Germany's very first UNESCO World Heritage Site in 1978. In 2023, the ancient seven-year pilgrimage resumed, continuing seven centuries of living Catholic tradition.
Architecture & Facilities
Aachen Cathedral represents an exceptional architectural palimpsest merging Carolingian Pre-Romanesque ingenuity with High Gothic soaring verticality. Designed by Odo of Metz, its core centralized octagon mirrors Byzantine imperial basilicas such as San Vitale in Ravenna, utilizing heavy masonry piers and barrel-vaulted tribunes to create the earliest monumental stone vault north of the Alps. The daring fifteenth-century Gothic choir dissolves stone load-bearing walls into radiant fields of stained glass, uniting earthly imperial monumentality with transcendent heavenly light.
Building Materials
Sandstone and Belgian Limestone
Local Devonian gray sandstone and dense Namur limestone provide the structural masonry core.
Classical Marble Spolia
Thirty-two antique Italian marble and porphyry columns hauled from Rome and Ravenna adorn the arcades.
Wrought Iron Tension Rings
Concealed Carolingian forged iron tie-bars encircle the octagonal clerestory to counteract outward vault thrust.
Gilded Copper and Bronze
Imperial Romanesque metalwork forms the massive Barbarossa Chandelier and monumental entrance doors.
Interior Features
The Carolingian Octagon
A centralized two-story dome vault rising over thirty-one meters supported by eight heavy piers.
The High Gothic Choir
A radiant sanctuary surrounded by thirteen towering stained-glass lancets housing the golden shrines.
The Hochmünster Gallery
The elevated second-story stone arcade that preserves the historic coronation throne of Charlemagne.
The Hungarian Chapel
An eighteenth-century baroque side chapel designed by Johann Joseph Couven to serve foreign pilgrims.
Temple Grounds
The cathedral anchors the historic center of Aachen, flanked by the pedestrian Katschhof square, the Gothic City Hall, and landscaped stone courtyards that outline the original palace precinct.
Additional Facilities
The nearby Dom-Information visitor center coordinates guided architectural tours, while the adjacent Aachen Cathedral Treasury showcases medieval liturgical goldwork and imperial relics.
Religious Significance
Aachen Cathedral occupies a singular place in Western Catholic theology and the wider Abrahamic tradition of sacred space, embodying the physical manifestation of the heavenly City of God on earth.
To serve as the mother church of the Diocese of Aachen, a sanctuary for royal consecration under God's grace, and an enduring pilgrimage shrine housing foundational relics of salvation history.
Sacred Ordinances
The Holy Sacrifice of the Mass
Daily Catholic Eucharistic liturgy celebrated at the high altar to renew Christ's redeeming sacrifice.
Imperial Coronation Anointing
Sacramental royal anointing and enthronement signifying that secular authority is subordinate to divine justice.
Relic Veneration (Heiligtumsfahrt)
The septennial public veneration of the four great garments associated with Christ, Mary, and John the Baptist.
The Celestial Jerusalem on Earth
Charlemagne and his ecclesiastical advisors drew directly upon the Book of Revelation to fashion the Palatine Chapel as an architectural icon of the New Jerusalem. The eightfold symmetry of the Carolingian Octagon signifies the Eighth Day—the eternal day of resurrection that transcends earthly creation. Suspended beneath the central dome, the Barbarossa Chandelier with its forty-eight lamps and sixteen symbolic gates renders the celestial city physically tangible to worshipers below.
Incarnational Pilgrimage and Relics
Catholic sacramental theology views sacred relics not as idols, but as tangible witnesses to the mystery of the Incarnation. The four great Aachen relics—the Virgin Mary's cloak, the swaddling clothes of the infant Jesus, the loincloth of the Crucifixion, and the cloth of John the Baptist's martyrdom—anchor the pilgrim's faith in the physical reality of Christ's birth, redemptive passion, and resurrection.
