The Kaḷinga architectural style is a style of Hindu architecture which flourished in the ancient Kalinga previously known as Utkal and part of the kingdom of Magadha and in present eastern Indian state of Odisha. The style consists of three distinct types of temples: Rekha Deula, Pidha Deula and Khakhara Deula. The former two are associated with Vishnu, Surya and Shiva temples while the third is mainly with Chamunda and Durga temples. The Rekha Deula and Khakhara Deula houses the sanctum sanctorum while the Pidha Deula constitutes outer dancing and offering halls.
