Bhubaneswar is called the Ekamra Kshetra as the deity of Lingaraja was originally under a mango tree (Ekamra) as noted in Ekamra Purana, a 13th-century Sanskrit treatise. The temple is active in worship practises, unlike most other temples in Bhubaneswar and Shiva is worshipped as Harihara, a combined form of Vishnu and Shiva. The temple has images of Vishnu, possibly because of the rising prominence of Jagannath sect emanating from the Ganga rulers who built the Jagannath Temple in Puri in the 12th century.
