Saint-Géry Island or Sint-Goriks Island was the largest island in the river Senne in Brussels, Belgium. It was named after Saint Gaugericus of Cambrai, who according to legend, built a chapel there around 580. It ceased to exist as an island when the Senne was covered over in the late 19th century, and a former covered market, the Halles Saint-Géry/Sint-Gorikshallen, was built in its centre. Since the late 20th century, this building has been rehabilitated as an exhibition space.
