Obvodny Canal
Obvodny Canal is the longest canal in Saint Petersburg, Russia, which in the 19th century served as the southern limit of the city. It is long and flows from the Neva River near Alexander Nevsky Lavra to the Yekaterinhofka River not far from the seaport. The canal was dug in 1769–1780 and 1805–1833. By the late 19th century, after the Industrial Revolution, it had effectively become a sewer collecting wastewater from adjacent industrial enterprises. Eventually the canal became shallow and no longer navigable. The banks of the canal are lined with granite.
