The real image from La Sagrada Família is:
Image #4
Some clues that give away the AI images:
🧱 1. Stonework and Structure
Real (Image #4): The stone is irregular in texture and construction, especially around the edges where you can see subtle imperfections and natural wear. The surrounding architecture has Gaudí’s signature flowing, organic forms and asymmetry.
AIArtificial Intelligence (AI) is basically when computers get smart—really smart. Imagine if your c... More (Images #1–3):
#1’s columns are too smooth and evenly spaced, almost like molded plastic.
#2 and #3 have overly symmetrical architecture with slightly “too perfect” spacing between elements — a common AI slip-up.
🎨 2. Stained Glass Color Transitions
Real: In #4, the stained glass features smooth and organic transitions between colors — reds melting into oranges, blues into greens. The light coming through feels diffused and natural.
AI:
In #1, the colors are overly saturated and laid out almost like a rainbow gradient.
#2 and #3 have inconsistent patterns and light distribution that don’t quite match how real sunlight filters through glass.
🌞 3. Lighting and Glow
Real: In Image #4, the light cast on the stone surfaces around the window feels authentically soft and directional. Some areas are brighter where the sun hits directly; others are dimmer and shadowed.
AI: In the other images, the lighting often feels painted on or too evenly distributed across the entire surface.
🌹 4. Rosette Window Detail
Real: The rose window in #4 has an almost floral, asymmetrical design with deep blue hues and uneven spacing between the petals. It looks like stained glass that was handcrafted — not generated.
AI:
In #1 and #3, the rosettes are perfectly circular with repeated patterns.
#2 features oddly shaped panes and strange overlaps that don’t quite match any known real-world design.
La Sagrada Família is the most jaw-dropping structure I’ve ever had the good fortune to visit. Its architecture and beauty in unparalleled. Located in Barcelona, this church has been under construction for over 130 years. Check out the video below for a short, but fascinated, tour and history of this world treasure.
