The Borra Caves are believed to be millions of years old, formed by the continuous flow of the Gosthani River eroding the limestone rocks. The caves were discovered by British geologist William King in 1807. Local tribal communities have long known about the caves, but it was King's documentation that brought them to the attention of the wider world. Over the years, the caves have been developed for tourism, with pathways, lighting, and viewing platforms added to make them accessible. The caves also hold religious significance for the local people, with a small Shiva Lingam found within, which is believed to be naturally formed. The caves continue to fascinate geologists and visitors alike, offering a unique insight into the earth's geological history.
