 Odisha state, East India  has innumerable popular Hindu temples and the temple architecture native to this place is far different from those in south India. But the basic plane is similar except in many temples the sanctum has a tall tower or gopura. As for stone sculptures  some of the temples are  well-known for eroticism. Both Vishnu and Shiva temples are widely distributed over the state along with Buddhist temples.
A protected monument maintained by the Archaeological Survey of India ASI),  the Varahanatha Temple, also known as Yajna Varaha Temple  is located at an elevated place  on an island created by two branches of the Vaitarani River, about 1 km (0.62 mi) from Jajpur  called as Biraja Kshetra in Odisha.  But it is prone to flooding when the rive is in spate . It is home of the sacred temple of goddess Biraja. In the  temple complex the main shrine is dedicated to  Varaha (meaning boar), an avatar of the God  Sri Vishnu. Included in this temple  that was built in the 15 and 16th century are many small shrines of other deities such as Shiva, Vishnu, Vimala and others. The temple follows the native  architectural style called  Kalinga. Somavamshi King, Jajati Kesari` ruled  this place in early 10th century. Besides main shrines, there are  other  shrines in the complex : Gadadhara Vishnu shrine, a shrine to the sun-god Surya, Kasi Biswanath temple (a form of  Shiva) and a shrine to saint Chaitanya.

The Hindu mythological  legend has it Trinity God Brahma (creator) in the midst of Ashvamedha yajna  (fire ritual) -  found out  that the Vedas (scriptures) had been  stolen. So, he sought the help of God Vishnu (protector)  to retrieve them to  complete the Yajna. God Vishnu took the avatar of a boar (an anthropomorphic form with a boar's head and human body; it is the third avatar to retrieve the earth from the ocean) and emerged from the sacrificial

fire  with the stolen scriptures. The yajna is purported to have taken place here and this place is called  Jajfiapura or Jajpur.  Since the weapon of Varaha is mace this  place is known as Gada Kshetra  (after the gada mace) 

As to the builder of this temple, there are different versions and it is a subject of discussion. It is mentioned that this temple complex came up  during the reign of the Suryavamshi Gajapati  in the 15–16th century.  The chronicle  Madala  Panji claims the builder of this temple was  Prataparudra Deva (reign: 1497-1540). Yet other  version mentions about  the king's head priest, Kasi Mishra. 
Chaitanya Mahaprabhu (1486–1534) is said to have visited this temple in 1510 and sanctified this place.  Raghoji I Bhonsle (reign: 1739–1755), the Maratha ruler of Nagpur kingdom carried out major repairs and strengthened the Temple.
