The Basilica church of St. Ursula (pronounced as /de/, ˌtsɪnt ˈʔoʒəla/) is located in Cologne, North Rhine-Westphalia, Germany. It is built upon the ancient ruins of a Roman cemetery, where the 11,000 virgins associated with the legend of Saint Ursula are said to have been buried.[1] The church has an impressive reliquary created from the bones of the former occupants of the cemetery. It is one of the twelve Romanesque churches of Cologne[2] and was designated a Minor Basilica on 25 June 1920. While the nave and main tower are Romanesque, the choir has been rebuilt in the Gothic style.
The Golden Chamber, or Goldene Kammer, of the church contains the alleged remains of St. Ursula and her 11,000 virgins who are said to have been killed by the Huns, possibly around the time of the Battle of the Catalaunian Plains.
There are various theories relating to the origin of the legend of the 11,000 virgins - one is that the original legend said 11 virgins accompanied St. Ursula, but later readings misread the abbreviation "M" for martyrs as Latin numeral "M" for 1000, which over time lead to 11,000.
The walls of the Golden Chamber are covered in bones arranged in designs and/or letters along with relic skulls. The exact number of people whose remains are in the Golden Chamber remains ambiguous but the number of skulls in the reliquary is greater than 11 and less than 11,000. These remains were found in 1106 in a mass grave and were assumed to be those of the legend of St. Ursula and the 11,000 virgins. Therefore, the church constructed the Golden Chamber to house the bones. The bones themselves are neatly arranged in "zigzags and swirls and even in the shapes of Latin words."[3]
