浮遊するリング：中央がくり抜かれた美術館

Design a museum in the manner of Gordon Bunshaft's Hirshhorn Museum — a windowless concrete drum lifted clear of the ground on four massive piers, with a circular open court cut through its middle so the building is a hollow ring rather than a cylinder. Compose a sheer aggregate concrete cylinder with one long horizontal window slot on the inner court face only, four huge piers leaving the ground plane open beneath, a sunken sculpture garden alongside, a fountain in the round court, hard bright light on the blank curved wall, low three-quarter view, 24mm lens, architectural photography, ultra photorealistic, 8K
