Another temple called Nandi-teertha, which was reported by some agencies to be 400 years old, was re-discovered in 1997 AD during excavation work in a place south-east of the Kadu Mallikarjuna temple. However,
B N Sundara Rao in his book, Bengalurina Itihasa, has documented that the late Rao Bahadur
Yele Mallappa Shetty constructed this Kalyani along with the Nandi, and the Shiva-linga. The Kalyani was constructed sometime after the construction of Sankey tank in about 1882 AD. Downward stream from the Sankey tank was observed to be flowing towards the place by Mallappa Shetty. He constructed a conduit pipe from here to the mouth of the Nandi so that water flows gently through the mouth of the Nandi throughout the year onto a Shiva-linga idol (Nandikeshwara) which was set right underneath. This water was then channelled to a Kalyani (stepped tank) which is at a lower level such that excess water flowed onto a well found in the garden in front of the southern entrance of the temple. This was connected to a storm water drain (raja-kaluve) which emptied the excess into another tank bund called Jakkarayana kere. This network has unfortunately been encroached upon. Surrounding the Kalyani is a double storeyed colonnaded structure. A shrine to Ganesha is also present in the vicinity. This, along with the Kadu Mallikarjuna and Gangamma temples, marks the linkage of the sacred to a natural node now. ==1997 rediscovery==
