The Submerged Stones of Gupta Kashi & the Tea Gardens
Carved out of Sonitpur district in 2015, Biswanath is a scenic riverfront district located along the northern banks of the Brahmaputra River. The focal point of the district is **Biswanath Ghat**—popularly known as **Gupta Kashi**—featuring a cluster of ancient stone temples built along the riverbed that submerge completely under the summer monsoon floods.
The visual identity of Biswanath district is Biswanath Ghat turquoise and tea garden gold. Defining the district is **Biswanath Ghat** (with its historic Shiva temple), the massive **Monabari Tea Estate** (celebrated as one of the largest single tea gardens in Asia), and the **Brahmaputra channels** (where endangered Ganges river dolphins swim).
The historical core of the district is Biswanath Ghat, popularly referred to as *Gupta Kashi* (the Hidden Varanasi) due to its religious and archaeological importance. Built along the rocky banks of the Brahmaputra River, the site contains a cluster of ancient stone temples dedicated to Lord Shiva, dating back to the Ahom and Kamarupa periods. The most unique aspect of these temples is their seasonal submergence; during the peak monsoon season, the rising waters of the Brahmaputra completely submerge the stone shrines, leaving only the tops visible. Pilgrims and slow travelers visit the ghat during the dry winter months when the waters recede, revealing the ancient stone carvings and rocky riverbed.
In terms of economy and landscape, Biswanath is dominated by the sprawling Monabari Tea Estate, recognized as one of the largest single tea plantations in Asia. Managed by major tea conglomerates, the estate covers thousands of acres of rolling green hills, dotted with shade-providing trees and worker settlements. The estate produces high-quality Orthodox and CTC teas that are exported worldwide. Visiting the estate offers travelers an insight into the unique lifestyle of the tea-tribe community, who have developed their own distinct folk dances, such as the *Jhumur*, and a rich oral storytelling heritage that centers around the tea bushes and the seasonal rhythms of plucking.
The geography of Biswanath is also defined by the complex riverine channels of the Brahmaputra, which form wide sand islands (*Chaporis*) that serve as critical habitats for rare wildlife. The deep river pools near Biswanath Ghat are home to the endangered Ganges River Dolphin, locally known as the *Sihu*. The local fishermen have formed conservation committees to protect these mammals from illegal nets and water pollution. The river channels also attract migratory waterfowl from Siberia during winter, making the riverbanks a paradise for birdwatchers who explore the sandy islands on traditional wooden country boats.
"Where the Brahmaputra rises to cover the ancient stone carvings of Biswanath Ghat, the rolling green slopes of Monabari produce the finest golden leaf tea."
