A Hindu temple is a pancharatha when there are five rathas (on plan) or pagas (on elevation) on the tower of the temple (generally a shikhara). The rathas are vertical offset projection or facets. The name comes from the sanskrit Pancha (=five) and Ratha (=chariot), but the link with the concept of chariot is not clear.
There are also temples with three rathas (triratha), seven rathas (saptaratha) and nine rathas (navaratha).
