The Golden Chamber
This walk-in reliquary chamber was endowed in 1643 by a merchant to bring together the bones that had previously been scattered throughout the church interior. According to legend, these are the remains of Ursula's 11,000 companions. Also on display are reliquary busts — gilded and silver-adorned wooden busts containing actual skulls and bones inside. Despite the widespread destruction of Cologne's city centre during World War II, the room survived largely intact and remains almost entirely in its 17th-century original state.
History
A succession of sacred buildings stood on the Roman burial ground from the 4th century onwards; the earliest three-aisled structure is said to have been expanded around 400 by the Roman senator Clematius. Around 922, Archbishop Hermann I established a noble women's convent here, which at its height in the High Middle Ages housed up to 40 canonesses. The current Romanesque building was constructed in the second quarter of the 12th century as a three-aisled gallery basilica; around 1247–1267 the large Gothic choir was added on the eastern side, its eleven windows encasing it like a "glass shrine."
The Clematius Inscription
Set into the south wall of the long choir since the 13th century, the Clematius Inscription is considered the earliest written evidence of Christianity in Cologne. It forbids, under threat of eternal damnation, the burial of anyone other than the holy virgins within the basilica. It is seen as the seed from which the legend of Ursula grew — though how the original eleven companions eventually became 11,000 remains unexplained.
Today
The basilica has been a pilgrimage destination for centuries and serves today as a memorial to the martyrdom of Christian men and women. The legend of Ursula lives on in Cologne's coat of arms.
