German Quarter
State-run factories established by Peter I on the Yauza provided the seed for a chain of private factories; by the end of the 18th century significant industrial clusters emerged in Lefortovo and former German Quarter (then practically devoid of Western-European influence). In 1846, pollution from these mills prompted Moscow governor Aleksey Shcherbatov to survey the banks of the Yauza and enforce administrative action against the offenders.
