Malleswaram is one of the areas in Bangalore where you can find many Hindu Temples. It has old Hindu constructed using the Dravidian architecture which were built during King Venkojirao Bhonsle of Thanjavur's (17th century B.C.) like the Kadu Malleshwara temple. Other famous temples in the area are Lakshmi Narasimha Temple, Sri Krishna temple, Circle Maramma Temple, Kannika Parameshwari Temple.
The 17th cross, 2nd main road, Temple Street is adorned by various temples. One among them is Nandi Teertha Temple. Here one can see water fall onto an idol of Shiva through the mouth of Nandi. This was discovered in the year 1999, but it has stood for 7,000 years on that spot. Being buried over the years hasn't diminished its aura at all. The temple was completely buried and the land above it was a flat stretch. When the land was dug, they found buried underneath, this temple and it was in perfect condition, preserved by the thick layers of soil. This underground temple was enclosed within a stone cut courtyard supported by ancient stone pillars. At the far end of the courtyard, a Nandi was carved out of a black stone with eyes painted in gold. From its mouth a clear stream of water flowed directly on to a Shivalinga made out of the same black stone at a lower level. There were steps that led to a small pool in the center of the courtyard where the water flowed and collected. The pool's center had a 15 feet deep whirlpool.
Nobody knows where the water comes from and how it passes from the mouth of the Nandi idol on to the Shivalinga. Nobody knows how the whirlpool came into being, the source of water, the sculptor, even the time when it was built remains a mystery.
