The Shrine of the Three Kings is approximately 43 inches (110 cm) wide, 60 inches (153 cm) high, and 87 inches (220 cm) long. It is shaped like a basilica: two sarcophagi stand next to each other, with the third sarcophagus resting on their roof ridges. The ends are completely covered, so there is no space visible between the sarcophagi. The basic structure is made of wood, with gold and silver overlay decorated with filigree, enamel, and over 1000 jewels and beads. The latter include a large number of cameos and intaglio pieces, some pre-Christian.
The entire outside of the shrine is covered with an elaborate decorative overlay. There are 74 high relief figures in silver-gilt in all, not counting smaller additional figures in the background decoration. On the sides, images of the prophets decorate the lower part, while images of the apostles and evangelists decorate the upper part. On one end, there are (across the bottom, from left to right) images of the Adoration of the Magi, Mary enthroned with the infant Jesus, and the Baptism of Christ, and above, Christ enthroned at the Last Judgement. The other end shows scenes of the Passion: the scourging of Christ (lower left) and his crucifixion (lower left) with the resurrected Christ above. This end also has a bust of Rainald of Dassel in the center.
