Lake Anosy [anˈuːsi] is an artificial lake in the southern part of the capital city of Madagascar, Antananarivo, about two miles south of Haute-Ville. Ampefiloha is located to the west of the lake, Isoraka to the northwest and Mahamasina to the north.
A swamp was replaced with Lake Anosy during the era of the ruler Radama I. The lake was constructed by James Cameron who gave it a shape of a heart. In the middle of the lake, there is an island connected with the city by an isthmus. From Wikipedia
