The Rue de la Loi or Wetstraat (Dutch), meaning "Law Street", is a major street running through central and eastern Brussels, Belgium, which is famous due to the presence of several notable Belgian and European Union (EU) governmental buildings. The road runs from the Rue Royale/Koningsstraat, in central Brussels, to the Robert Schuman Roundabout in its European Quarter. It forms the first (westerly) part of the N3 road that runs to Aachen, Germany.

The Robert Schuman Roundabout, sometimes called Robert Schuman Square, is a roundabout at the end of the Rue de la Loi/Wetstraat in Brussels, Belgium, that serves as a focus for major institutions of the European Union (EU). It is named after Robert Schuman, one of the founding fathers of the European Union, and gives its name to the surrounding district and Brussels-Schuman railway station.
