Visitors to a former royal chapel in Paris famed for its 13th-century stained glass can now study intricate details of windows towering 100 feet above their heads thanks to a smartphone app launched by one of the monument’s volunteers.
Commissioned by French King Louis IX to house relics including Jesus’s Crown of Thorns, the Gothic Sainte-Chapelle contains 15 windows depicting 1,113 scenes from the Old and New Testaments of the Bible, most of which are too tiny to see from the floor.
