The Place Eugène Flagey (French, pronounced [plas øʒɛn flaʒɛ]) or Eugène Flageyplein (Dutch), usually shortened to the Place Flagey, or Flagey by locals, is a square in the Ixelles municipality of Brussels, Belgium. It bears the name of a former mayor of Ixelles, Eugène Flagey.
With ten streets converging there, the Place Flagey is one of the best connected crossroads in the city, directly adjacent to the neighbouring Ixelles Ponds. Until 1937, the square was known as the Place Sainte-Croix/Heilig-Kruisplein, but this name only now applies to the square in front of the Church of the Holy Cross on the south-western corner.
The Flagey Building, also known as the Radio House, is a remarkable Art Deco building, the former headquarters of the Belgian National Institute of Radio Broadcasting, and now houses Le Flagey cultural centre. It is located on the south-western corner of the square with its entrance on the Place Sainte-Croix.
