The Shrine is part of the late 12th century shrine tradition. It has the form of a
naved church, without a transept. It is an oak box 2.04 metres long, 0.57 metres wide, and 0.94 metres high (80.3in by 22.4in by 37.0in), decorated with gilt silver, gilt copper,
filigree, precious stones, and
enamel. The double step of the base is adorned with enamel plates, engravings, filigree, and
silver stamped with floral designs. The two long sides each show an
arcade of eight archways resting on double columns, in which the kings and emperors of the realm are enthroned. The front gable end shows Charlemagne enthroned, with
Pope Leo III standing to his right and Archbishop
Turpin of Rheims to his left. A half-figure of
Christ is located in a
medallion above Charlemagne. On the rear gable end the
Madonna with Christ is enthroned between the
Archangels
Michael and
Gabriel. Three half-figures, the personifications of Faith, Hope, and Love, are depicted above. The two surfaces of the roof show four reliefs with scenes from the
romanticised life of Charlemagne. A crest of gilded copper, with five towers, decorates the ridge and gable of the roof. Each of the long sides of the shrine depicts eight enthroned emperors. Shown on its right side, as viewed from the front gable end, are the following (from left to right):
Henry II,
Otto III,
Otto I,
Otto II,
Charles the Fat, an unnamed Emperor,
