National Library of Medicine, Bethesda, Maryland, June 16, 1961, peak of high roof: [construction]
Image caption on page 69 of the book US National Library of Medicine: "Two men inspect the peak of the eye-catching, pagoda-like roof of the new library building. The roof was in part a bomb-resistance feature, providing what its architect described as a pressure-relief opening near the center which would protect the collection from bomb-blast shock waves."
