The Butte-aux-Cailles(French pronunciation: is a hilltop neighbourhood of Paris, France, located in Paris' south-eastern 13th arrondissement. The name of the hill could be translated as "quail hill", but it actually originates from its former landowner Pierre Caille, who bought a vineyard here in 1543. The Bièvre river, which once made this area important for the tannery and tissue trades, was covered over in 1860.
