In this answer I also want to cover the adjacent temples of Hampi.
Hampi a beautiful city built by the great Vijayanagara empire is a must visited place in India.Hampi is situated on the banks of Tungabhadra river.
Vijayanagara empire founded by HariHara and Bukka was an empire that protected Sanatana Dharmam against the invaders.

1.Virupaksha temple is dedicated to Lord Shiva(Virupakshar and her consert Pampadevi) and is a UNESCO world heritage site.
2.Hampi is the place where Anjaneyar was born.The older name of this place is called as Kishkinda.
3. Actually the Virupaksha temple was built by Chalukyas in 7th century and later expansions were made by Krishnadevaraya.
4.Although the Bahamani sultans destroyed the city and adjacent temples,they didn’t even touch a single stone of this temple and even the Bhuvaneshwari temple(Goddess of Karnataka).
The reason why the sultans left this temple untouched is not clearly known.

5.The replica or shadow of the tower of Virupaksha Temple falls inverted inside the wall of the temple through a lens like hole structure.They have invented the method of Photography before 700 years- Really Stunning.
6.Near to this temple ,there is a Vittala temple(a Vishnu temple but now no Vigraham).This temple is destroyed but still the pillars stand very steadily
The 56 pillars are musical pillars(made of single type of stone) and if you hit the pillars with your fingers,you can here the basic tone of Carnatic music-Sa re ga ma.
Its really a wonder to me “ How did they made the music to come out of a stone?”
Even Tamil Nadu also has these type of musical pillars in 3 temples and some say that the music produced in this Vittala temple is very different than others and changes according to the weather.
7. In front of this Vittala Temple there is a single stone carved huge chariot.
8. There is a Badavilingeshwara temple in Hampi.Its a Underground Shiva temple.
This temple was built by the money gathered by a poor women who wished to build a temple for Lord Shiva and hence this temple is simple.The temple is constructed in a such a way that sun’s rays always fall on Lingam.The Lingam is nearly 3m height and a spring of water always flows around the Lingam.
You should walk in water and I am not pasting the image of Lord Shiva and I want you people to come and take his blessings.
