This temple is a remarkable example of Dravidian architecture in the 8th century due to its almost accurate proportions and intricate workmanship by a set of dedicated sculptors in a time when there must have been only hand tools available for construction and elephants for transporting heavy building material.
It was sanctioned for construction by Krishna I, the king belonging to the Rashtrakuta dynasty which ruled over the large parts of the Indian Subcontinent between the sixth and the tenth centuries.
This temple is estimated to have been built between 757 and 783 BCE with a view to liken Mount Kailash, where Shiva is believed to reside as per Hinduism.
An estimated 400,000 tons of rocks were scooped out over a really long period of 20 years to construct this monolithic structure.
By observing the chisel marks on the stone walls, archeologists have come to the conclusion that three types of chisels were used to carve this temple.
This temple is believed to have been constructed vertically from the top down due to foreseen difficulties in carving out the frontward by the main architect who has religiously followed the construction according to the ground plan as seen in the below picture.
Multi-level carvings are seen over a two storied gateway which opens to reveal a U-shaped courtyard edged by a columned arcade three stories high which consist of huge sculpted panels containing large sculptures of a variety of deities.
An image of the bull Nandi is seen in front of the main sanctum sanctorum which is a tradition seen in all temples dedicated to Lord Shiva.
The temple’s base has many elephants carved into them which is to bring out the idea that the entire temple is being held aloft by these elephants.
The internal shrine of the temple consists of pillars, windows, inner and outer rooms, gathering halls, and an enormous stone lingam at its heart within the sanctum sanctorum and is carved with images of various deities, erotic male and female figures, and many others.
Most of the deities at the left of the entrance are believed to be followers of Lord Shiva while on the right-hand side the deities are believed to be followers of Lord Vishnu, another main deity in Hinduism.
In today’s world where we are dependent upon technology for everything, it is hard to imagine an era nearly twelve centuries ago where our ancestors could build an entire structure out of hard rock using a few hand tools with their bare hands and that too with such extreme dedication and devotion.
