The Ixelles Ponds (French: Étangs d'Ixelles, Dutch: Vijvers van Elsene) are two freshwater ponds in the Brussels municipality of Ixelles. The ponds we can see today are those spared by a 19th-century campaign of drying the wetlands of the Maalbeek valley between La Cambre Abbey and Flagey Square.The two long and narrow ponds, whose total lengths are approximately 700 metres (2,300 feet), and widths are approximately 50 metres (160 feet), are aligned on a roughly North-South axis and are separated by a narrow strip of land.
