Mananchira is a man-made freshwater pond situated in the centre of the city of Kozhikode in Kerala, southern India. Mananchira was built as a bathing pool by the Zamorin Mana Vikrama, the feudal ruler of Kozhikode in around the 14th century. This beautiful park once used to be a palace tank of King Vikrama, the last Zamorin King, who designed it to meet the water requirement of the town. The tank has been preserved almost in its original form and continues to supply water to the people of the city. The sprawling estate adjoining the tank is now partly converted into a park with important buildings also coming under the same area, including the Public Library, Town Hall, and Commonwealth Trust Office. The Mananchira Square now includes an artificial hill, sculptures, an open-air theatre, a musical fountain, trees, plants, and shrubs. It gives a pleasant atmosphere to the visitors and make them feel relaxed even when the day is super hot or humid. The Mananchira Square got its name from a man-made lake Mananchira, located in the centre of the city. The lake on the other hand is named after Manadevan Samoothiri, the erstwhile ruler of the Kozhikode Kingdom. The pond is an important source of drinking water for Kozhikode, but is susceptible to pollution from municipal sewage, domestic waste, and pollutants from nearby textile factories. An analysis of the water in 2000 by scientists from the Central Water Analysis Laboratory and Pondicherry Central University found that the pond was particularly bacteriologically contaminated during the monsoon season, and was highly alkaline afterwards.
