"The abandoned towers in Isfahan, Iran feature a honeycomb-designed interior, which was beautifully constructed for a pretty gross purpose. No two towers were built alike, they're all designed differently. Each tower was built to house between 5,000 and 7,000 pigeons. Why? To collect their droppings for fertilizer. Pigeons were often prey during the nighttime, so the towers provided them protection."

Some beautiful pics that didn't want to be included.

It's amazing so much effort was expended to collect fertilizer.

Not unusual. Fertilizer is a big deal. They actually sailed to islands to collect bird and bat guano and fortunes were made selling it. The discovery of the Haber Process to synthesize nitrogen fertilizer was one of the great turning points.

So maybe we have it wrong. The great pyramids were just great shit collecting machines :-)
