The answer

Bayon face tower, Angkor Thom, Siem Reap, Cambodia · KH · Photographed 1866

How the AI detective did

The AI placed its guess 40 km from the real location (it guessed Beng Mealea, Cambodia).

This is the Angkor heartland under jungle — but I choose the unrestored sprawl of Beng Mealea east of the capital, a decade late on the expedition date.

The evidence the AI read

• architecture: A ruined stone tower carved with colossal serene faces gazes out of the frame; corbelled doorways and toppled blocks lie beneath it. — Face-towers of a god-king's temple-city — the signature of one vanished mainland Southeast Asian empire's capital-building tradition.
• vegetation: Strangler figs, lianas and young trees envelop the masonry, and dense forest presses in on every side of the ruin. — Long abandonment in a hot monsoon forest — a lost city being reclaimed by jungle, not a maintained shrine.
• terrain: The ground is a chaos of fallen blocks and leaf litter, with no cleared paths, fences or visitors anywhere in the frame. — Photographed before any restoration or tourism: an interior site reached by expedition rather than by road.
• era_marker: A sepia wet-plate image with ragged edges, chemical stains and light leaks; the long exposure needed full daylight. — A wet-collodion glass plate — the expedition photography of the 1860s-70s, among the first cameras ever carried to this place.
