"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."
