The Brussels Ring (R0) crosses through the three Regions (Flanders, Wallonia and the Brussels-Capital Region).
The biggest part of the R0 (in the North, East and West) belongs to Flanders. A southern part of the R0 belongs to Wallonia. Multiple smaller parts of the R0 are located on Brussels territory: in Neder-over-Heembeek, in Anderlecht and Vorst/Forest, and in Oudergem/ Auderghem and Watermaal-Bosvoorde/ Watermael-Boitsfort.
