NOTRE DAME CATHEDRAL, PARIS     Notre Dame, Paris, one of the most imposing and famous of cathedrals. The present structure was begun in 1163, but is chiefly of the early 13th century; the facade, with its three large portals, great roses, gallery and arcades and twin square towers, is one of the two or three finest produced by pointed architecture.
    The transept-fronts are unsurpassed in their way, and the long range of windows and flying buttresses of nave and choir is highly effective. The figure and foliage sculpture of the exterior is abundant and artistically remarkable. The graceful rood-spire was built by Viollet le Duc in place of the original one. The interior, with nave and double aisles continued around the choir, measures 156 by 4,022 feet and 110 feet high. The three roses retain their original glass, but the remainder of the glass is modern. The choir-screen is carved with interesting New Testament relief of the 14th century.
