Red Canal

The [Red Canal](https://en.wikipedia.org/wiki/Red_Canal) was an 18th-century Saint Petersburg waterway dug between **1711** and **1719** to help drain marshy ground between the **Moyka** and **Neva**. It was filled in during the late **1770s**, and the former channel helped define the west edge of what is now the **Field of Mars** area.
