The south portal, or Portal of the Virgin, dates to about the 1220s, the same time as the Pillar of the Angels and the Astronomic clock in the interior. Decrees of the Emperor rendering justice were traditionally read out in front of this doorway. The rounded arches of tympanum over the doorway contain sculpture of the Virgin Mary dying, surrounded by the Twelve Apostles and being crowned by Christ. The original statue-columns of the Apostles from the 1220s which supported the tympanum were smashed in 1793 during the French Revolution.
