The Latium town of Tivoli lies next to the Aniene River which, on occasion, would flood well beyond its banks, causing great damage to the surrounding town. Pliny the Younger recorded such devastation in A.D. 105, with other catastrophic events occurring in 1688, 1689, and 1826. After that latest diluvial chaos, Pope Gregory XVI intervened, with the river being diverted via a massive earthworks project that ultimately created two underground tunnels and a charming cascade. Overall, it was a highly celebrated feat of civil engineering.
