Other temples built are in a blend of Nagara style (north Indian architecture) and Dravidian architecture, also called as Vadara style. One depiction of Vishnu in the state dates back to the 6th century. The Bhoga Nandeeshwara Temple in Nandi village is one of the oldest temples in Karnataka dating to the 9th century. The temple, hewn out of rock, comprises two complexes. While the first complex houses three deities, the second complex consists of a huge and majestic kalyani or pond. The foundation of the temple was laid by the Banas of the 9th century. The Chola rulers of the 11th century constructed the roof of the temple. The marriage hall was built by the Hoysalas in the 13th century and a wall of the second complex was built by the Vijayanagar kings. Stone carvings are a popular tourist attraction and are a source of inspiration for students of art and architecture.
