Somewhere in the salt desert between Qom and Varamin, eighty kilometers from either city and thirty-five from anything resembling a town, an enormous rectangle of brick and plaster rises from the flat earth. Dayr-e Gachin has stood here since the Sasanian Empire, when Ardashir I ordered its construction in the 3rd century AD. The name translates roughly as "plaster dome," referring to a gach dome that once crowned the structure but has long since disappeared.

This was not merely a rest stop. It was a self-contained world, engineered to keep humans, animals, and cargo alive in one of the harshest landscapes on the Iranian Plateau.

The truth likely splits the difference: Ardashir built the original, and Anushiruwan rebuilt it during his 6th-century reign. T...
