The opening of the Century 21 Exposition on April 21, 1962 transformed the image of Seattle and the American Northwest in the eyes of the world. The region, which had been known until that point more for its natural resources than as a cultural capital, established a new reputation as a center of emergent technologies and aerospace design. This new identity was embodied by the centerpiece of the exposition: the Space Needle, a slender assemblage of steel and reinforced concrete which became—and remains—Seattle’s most iconic landmark.[1]

The origin of Gothic architecture, a style which defined Europe in the later Middle Ages, can be traced to a single abbey church in the northern suburbs of Paris. The Basilique royale de Saint-Denis (Royal Basilica of Saint-Denis), constructed on the site of an abbey and reliquary established in Carolingian (800-888 CE) times, was partially rebuilt under the administration of Abbot Suger in the early 12th Century; these additions—utilizing a variety of structural and stylistic techniques developed in the construction of Romanesque churches in the preceding centuries—would set medieval architecture on a new course that would carry it through the rest of the epoch.
