Stand in a Trastevere basement and you can look straight down through glass at a Roman street eighteen feet below the one you're standing on. That's not a curiosity. That's the whole city.
Rome was never built once. It was built roughly six times, in overlapping layers, on top of itself, and it never really stopped. Most histories march through emperors and dates until the story runs out of centuries. This book does something different: it follows the physical systems instead, the walls, the drains, the concrete, the roads, the buildings, in the order the city actually laid them down.
You'll learn why Roman concrete gets stronger in seawater while modern concrete crumbles. Why the Colosseum is pockmarked with thousands of small holes. Why a medieval pope burned masterwork statues for mortar, and why that wasn't vandalism so much as it was survival. Why Mussolini's bulldozers cut straight through the ancient Forum, and what a subway crew still finds every time they try to dig a new tunnel today.
By the end, you won't just know Rome's history. You'll know how to read it, standing on any street corner, in any century's leftover stone. This is a book for people who want to actually see the city they're walking through, not just photograph it.
