Sainte-Chapelle: Paris, France
The 15 huge stained-glass windows in this Gothic chapel on Paris’ central Ile de la Cité depict scenes from both the Old and New Testaments. The 6,458 square feet of mostly red and blue glass depict 1,130 biblical figures, reports The Guardian, and recently underwent a painstaking seven-year renovation. The chapel was built in the 1240s and included the 50-foot tall windows. A stained-glass rose window was added a century later.
