The Maelbeek or Maalbeek (Dutch pronunciation: [ˈmaːlbeːk]) is a stream that runs through several municipalities in Brussels, including Etterbeek, Ixelles, St-Josse-ten-Noode, Schaerbeek. It is a tributary of the Zenne, which it joins up in Schaerbeek, from its source located to the south near the Abbey of La Cambre. The name Maalbeek, (meaning mill brook), comes from the Dutch words beek (meaning brook) and maal (meaning to mill). Molenbeek has a similar derivation. It was vaulted in 1872, at which time there were 58 ponds along the stream. Nowadays, only six are left: the ponds of the Abbey of La Cambre; of Ixelles (two); of Leopold Park; of Marie-Louise Square; and of Josaphat Park.
