The cathedral has three portals, corresponding to the three vessels of the nave. Each has a particular theme of decoration; the left portal is dedicated to the infancy of Christ, the central portal to redemption, and the right portal to the Last Judgement. The portals are set forward from the front of the church by the network of slender columns, spires and arches which form an outer decorative wall. The sculpture largely dates to the late 13th century and is similar in theme and style to that of the sculpture of Reims Cathedral made between 1250 and 1260, though the Strasbourg sculpture shows greater realism.
