FLECHE, an architectural term which, in France, signifies any spire, but in English usage is limited to those small, slender spires which are placed on the ridge of a roof of a church and not upon a tower. The fleche is usually built of a wood frame work covered with lead or occasionally copper and is generally of rich, light, delicate design, in which tracery, miniature buttresses and crockets have an important part. They are frequently of great height, that of Notre Dame, Paris, being nearly 1 oof t. and that of Amiens, 148 feet. The Peke is usually placed at the inter section of nave and transepts. Reims cathedral had, however, an additional flecke at the summit of the apse.
