Donau-Schwarzmeer-Kanal
Work on the Danube–Black Sea Canal started in summer 1949, following the route marked by the Black Valley, stretching across Northern Dobruja from east toward west. The idea originated from a letter addressed by Stalin to Gheorghe Gheorghiu-Dej in 1948, and its purpose was far more than just for economic reasons. First of all, it was meant to be a social engineering project, with the declared aim of creating new technical and political staff. The communist regime in Bucharest could not finance such a massive undertaking; it was a politically driven project, meant to build up the "New Man", defined by the Marxist–Leninist doctrine.
