Borra Cave is located near the Ananthagiri hills of the Eastern Ghats range in Alluri Sitharaman Raju district, in Andhra Pradesh.
Borra Caves are ranked amongst the deepest as well as the largest caves in India that were formed millions of years ago.
These caves are considered to be among a rare geological formation and these were formed by the water activity by the Gosthani River.
Borra caves go as deep as 80 meters in depth and are karstic limestone structures.
These caves were discovered by William King George of the Geological Survey of India.
There is a naturally formed Shivling inside the caves, which is worshipped by the tribals who live in the nearby forests
The stalactites and stalagmites in the caves have various interesting shapes.
There are formations resembling Shiva-Parvati, Mother and Child, the beard of a saint, a crocodile and even a stalagmite in the shape of a human brain.
This structure is considered as an important discovery for anthropological research because excavations that were carried out unearthed some tools made of stone from tracing back to the Paleolithic age, some 30,000-50,000 years ago.
