One of the most ornate temples of the Dravidian style of temple Architecture, this 1200 year old Bhoganandeeswara Temple is rich in unique sculptural styles and inscriptions.
The Bhoganandeeswara temple complex has 3 temples (all dedicated to Lord Shiva) each built in a distinct style by dynasties of different ages.
'The Arunachaleshwara temple' was built by the Nolambas, 'Uma Maheshwara Temple' with ornate pillars was built by the Hoysalas and the main temple-' Bhoga Nandeeshwara Temple' with a majestic Shiva Linga was built by the Cholas. (Some Historians differ it was originally built by Ganga rulers. But if you take a closer look, you can definitely find Chola style in it. I think there might be some later additions by Cholas).
The Kalyana Mandapa and the Tulabhara Mandapa, the large temple tank and outer walls were later added by the Vijayanagara rulers.
Many of the sculptural niceties reminded me the sculpting style at Amirthakadeswara Temple at Melakkadambur, Tamilnadu.
