Aachen Cathedral: The Carolingian Royal Chapel That Became a Coronation Site for Thirty-One Kings

Countries & Cities · Published 29 September 2026 Swipe more like this →

In short: Constructed as the royal chapel for Emperor Charlemagne, this architectural marvel served as the coronation site for thirty-one German kings between 936 and 1531. Today, it stands as one of the earliest UNESCO World Heritage sites, blending Carolingian, Ottonian, and Gothic styles into a singular, enduring monument of European history.

Commissioned by Charlemagne around 796 and consecrated by Pope Leo III in 805, the Palatine Chapel was designed by Odo of Metz. Its core is a domed octagonal room, a structure that remained unsurpassed in height and span north of the Alps for over two centuries. The chapel was originally plastered in red, a color referencing its imperial status, and featured an interior lined with marble. Charlemagne himself was buried there in 814, and the site later became a major pilgrimage destination following his 1165 canonization.

The cathedral’s evolution reflects shifting architectural tides. In 1355, a Gothic choir hall—often called the Glashaus for its expansive windows—was added to accommodate the growing number of pilgrims. The site also houses extraordinary treasures, including the 11th-century Ambon of Henry II, a pulpit adorned with 6th-century ivory panels, and the Pala d'Oro, a golden altarpiece created around 1020. These pieces, alongside the throne of Charlemagne, underscore the cathedral's role as a repository of Carolingian and Ottonian artistry.

The cathedral survived the devastation of World War II, though it suffered significant damage from Allied bombing and ground fighting. Reconstruction efforts spanned over three decades and cost approximately €40 million. Today, the site continues its religious function, with relics like Christ's swaddling clothes and St. Mary's cloak displayed every seven years during the Great Aachen Pilgrimage, a tradition dating back to 1349 that draws thousands to this historic intersection of faith and imperial power.
