What is Temple tank?

Temple tanks are wells or reservoirs built as part of the temple complex near Indian temples. They are called pushkarini, kalyani, kunda, sarovara, tirtha, talab, pukhuri, ambalakkuḷam, etc. in different languages and regions of India. Some tanks are said to cure various diseases and maladies when bathed in. It is possible that these are cultural remnants of structures such as the Great Bath of Mohenjo-daro or Dholavira, which was part of the Indus Valley civilization. Some are stepwells with many steps at the sides.
