The austere brick exterior of the 13th century Sainte-Cécile Basilica Cathedral of Albi (or Albi Cathedral) reveals nothing about its opulent interior with its painted vaulted ceiling and columns, the Gothic lacy stonework in the Choir, the exquisite rood screen, and the 15th century mural of the Last Judgment under the monumental organ by Christophe Moucherel. The altar of the Church of the Canons within the Cathedral. The Choir of the Canons is hidden behind the rood screen which divides the Cathedral in two. It is decorated with a host of angels, the twelve apostles, the Virgin Mary, St. John the Baptist and St. Paul. The statue of Sainte Cecile, the patron saint of the Cathedral, is at the center of the screen below the crucifix. The figures of the emperors Charlemagne and Constantine face one another above the north and south entrances to the Choir. The ambulatory around the Choir is decorated with carved figures from the Old Testament. Notice the painted columns.
