Anji Bridge (Zhaozhou Bridge)
How did a single Sui-dynasty craftsman conceive and cut a flattened, open-spandrel segmental stone arch — a bridge form the West would not build for another 700 years — and execute it so soundly that its 37-metre span still carries visitors more than 1,400 years later?
