Mananchira is a man-made freshwater lake situated in the centre of the city of Kozhikode (Calicut) in Kerala, southern India. The lake is 3.49 acres (14,120 sq mt) in area, is rectangular in shape and is fed by a natural spring. Mananchira was built as a bathing pool by the Zamorin Mana Vikrama, the feudal ruler of Kozhikode in around the 14th century. The laterite obtained from excavating the tank was used to construct two palaces to the east and west. In the late 19th century, Calicut's municipal council decreed that the lake was to be reserved exclusively for drinking purposes, and prohibited its use for bathing, washing and recreational activities-a ruling that has remained in place ever since.
