Shravasti (; Pali: ) was a city of ancient India and one of the six largest cities in India during Gautama Buddha's lifetime. The city was located in the fertile Gangetic plains in the present-day district of the same name, Shravasti, that belongs to Devipatan Division of Uttar Pradesh near Balrampur, some north-east of Lucknow. Earlier, it was a part of the Bahraich district, but the latter was split due to administrative reasons.
Shravasti is located near the West Rapti River and is closely associated with the life of Gautama Buddha, who is believed to have spent 24 Chaturmases here. Age-old stupas, majestic viharas and several temples near the village of "Sahet-Mahet" establish Buddha's association with Shravasti. It is said that the Vedic period king, Shravasta, founded this town.
Shravasti was the capital of the Kosala Kingdom during 6th century BCE to 6th century CE. This prosperous trading centre was well known for its religious associations. Sobhanath temple is believed to be the birthplace of the Tirthankara Sambhavanath in Jainism, making Shravasti an important center for Jains as well. According to Nagarjuna, the city had a population of 900,000 in 5th century BCE and it even overshadowed Magadha's capital, Rajgir.
As mentioned in the 'Bruhatkalpa' and various Kalpas of the fourteenth century, the name of the city was Mahid. There are subsequent mentions showing that the name of this city was Sahet-Mahet. It is also mentioned that a vast fort covered this city in which there were many temples with idols of Devkulikas.
Today a great rampart of earth and brick surrounds this city. During excavation in 'Sahet-Mahet' near Shravasti City, many ancient idols and inscriptions were found. They are now kept in museums at Mathura and Lucknow. At present, the archaeological department of the Indian Government is excavating the site to perform allied research. Jetavana monastery was a famous monastery close to Shravasti.
