고딕 대성당 천문대 우주 도서관

Cinematic fantasy concept art of a vast celestial library inside a gothic cathedral observatory. Towering dark mahogany bookshelves rise into immense vaulted arches adorned with ornate bronze-gold filigree, intricate balconies, connecting bridges, and circular platforms. Shot from a wide-angle, floor-level panoramic perspective, featuring a polished black marble floor reflecting warm candlelight alongside flowing bands of luminous cosmic cyan starlight streaming across the ground. Exactly three spiral staircases: a grand sweeping staircase on the right with glowing step lights, a central spiral staircase wrapping around a tall cylindrical book tower, and a smaller spiral staircase on the left. Enormous arched windows open onto outer space, displaying nebula clouds, distant stars, planets, and a bright spiral galaxy through the upper left arch. Exactly two glowing blue celestial orbs sit on pedestals or tables, and exactly two open illuminated books rest on a foreground reading desk to the right. Lighting combines soft volumetric sunbeams, warm flickering candlelight, and radiant starlight with floating gold dust motes. Color palette: deep mahogany, antique gold, midnight blue, and vibrant cosmic cyan. Atmosphere is magical, quiet, and hyper-detailed. Constraints: no people, no readable text, no watermarks.
