The answer

Sagrada Familia, Barcelona, Spain · ES · Photographed ca. 1915

How the AI detective did

The AI placed its guess 84 km from the real location (it guessed Girona cathedral hill, Catalonia, Spain).

One sculpted facade and stub towers on an unfinished giant — Gaudí's church, surely; yet I commit up the road at Girona's cathedral hill and date the goat herd to 1925.

The evidence the AI read

• architecture: An enormous church rises unfinished: one richly sculpted facade with openwork spires stands nearly complete while bare walls, cranes and scaffolding trail behind it. — A cathedral-scale project in a wildly personal style — Gothic bones dissolving into art-nouveau sculpture, a single architect's lifework caught mid-build.
• terrain: The foreground is open waste ground behind a rough stone wall, and a herd of goats is being driven across it past a few onlookers. — The city has not yet reached its own great church — an urban fringe where farmland still touches the building line.
• vegetation: Young street trees stand bare-branched along a laid-out but barely built street grid. — A mild-winter Mediterranean city photographed in its planned expansion district.
• era_marker: A grainy monochrome print; only one facade and stub towers are complete, with timber cranes above the crossing. — The construction state is itself the date — early in the 20th century, decades from completion.
