History:
According to legend, the city was founded by the Hindu deity, Lord Shiva, around 5,000 years ago,thus making it one of the most important pilgrimage destinations in the country. It is one of the seven sacred cities of Hindus. Many Hindu scriptures, including the Rigveda, Skanda Purana, Ramayana, and the Mahabharata, mention the city.
Varanasi is generally believed to be about 3,000 years old. Varanasi was a commercial and industrial center famous for its muslin and silk fabrics, perfumes, ivory works, and sculpture. During the time of Gautama Buddha (born circa 567 BCE), Varanasi was the capital of the Kingdom of Kashi. The celebrated Chinese traveler, Xuanzang, attested that the city was a center of religious, educational, and artistic activities, and that it extended for about 5 km along the western bank of the Ganges.
Kashi Naresh and Ramnagar
Varanasi became an independent Kingdom of Kashi in the eighteenth century, and under subsequent British rule, it remained a commercial and religious center. In 1910, the British made Varanasi a new Indian state, with Ramanagar as its headquarters but with no jurisdiction over the city of Varanasi itself. Kashi Naresh still resides in the fort of Ramanagar. The Ramnagar Fort of the Kashi Naresh is situated to the east of Varanasi, across the Ganges. The Ramnagar Fort was built by Kashi Naresh Raja Balwant Singh with creamy chunar sandstone in the eighteenth century. It is a typically Mughal style of architecture with carved balconies, open courtyards, and picturesque pavilions. The other fort of the Kashi Naresh is the Chet Singh Palace, near Shivala Ghat, Varanasi built by Maharaja Chet Singh. Ramnagar Fort and its museum are the repository of the history of the kings of Benares and since the 18th century has been the home of Kashi Naresh. Even today the Kashi Naresh is deeply revered by the people of Benares. He is the religious head and the people of Benares consider him the incarnation of Lord Shiva. He is also the chief cultural patron and an essential part of all religious celebrations.

Geography:
The city of Varanasi is located in the middle Ganga valley of North India, in the Eastern part of the state of Uttar Pradesh, along the left crescent-shaped bank of the Ganga river. It has the headquarters of Varanasi district. The "Varanasi Urban Agglomeration" — an agglomeration of seven urban sub-units — covers an area of 112.26 km² (approximately 43 mi²). The urban agglomeration is stretched between 82° 56’E - 83° 03’E and 25° 14’N - 25° 23.5’N. Being located in the Indo-Gangetic Plains of North India, the land is very fertile because low level floods in the Ganges continually replenish the soil.
On a local level, Varanasi is located on a higher ground between rivers Ganga and Varuna, the mean elevation being 80.71 m. As a result of absence of tributaries and canals, the main land is continuous and relatively dry. In ancient times, this geographic situation must have been highly favorable for forming settlements. But it is difficult to ascertain the original geography of Varanasi because the city's current location is not exactly the same as the one described in some old texts.
Varanasi is often said to be located between two confluences: one of Ganga and Varuna, and other of Ganga and Assi [disambiguation needed], (Assi having always been a rivulet rather than a river.) The distance between these two confluences is around 2.5 miles, and religious Hindus regard a round trip between these two places—a Pancha-kroshi Yatra (a five mile journey) ending with a visit to a Sakshi Vinayak Temple as a holy ritual.
