In Hindu temple architecture, a ratha is a facet or vertical offset projection on the tower (generally a shikhara).
In Sanskrit, the word "ratha" means "chariot", but the link with this meaning is not clear.
The rathas are decorated with geometric figures or statues, such as statues of a gatekeeper watching outside or a niche with a statue of a deity.
Sometimes, the facet of the ratha is hollowed to the interior; these are rathas with recesses.
If there is only one facet, this is a temple with three rathas (triratha): the wall and the facet on the left and on the right.
If there are a main facet and a secondary one, the temple has five rathas (pancharatha). There are also temples with seven rathas (saptaratha). and nine rathas (navaratha).
