Shantiniketan or Santiniketan is a small town near Bolpur in the Birbhum district of West Bengal, India, approximately 165 km north of Kolkata (formerly Calcutta). It was established by Maharshi Devendranath Tagore, and later expanded by his son Rabindranath Tagore whose vision became what is now a university town, Visva-Bharati University.
Santiniketan was earlier called Bhubandanga (after Bhuban Mohan Sinha, the Zamindar of Raipur in WB), and was owned by the Sinha family. In 1862, Maharshi Debendranath Tagore, while on a visit to Raipur, showed interest in land near Birbhum. There was only one building there namely 'Santiniketan' (which is still there adjacent the upasana mandir known as 'Odisha Bhawan'). Maharshi liked the place and registered it in the name of Maharshi Devendranath against Rupee One as a token value. He called his home Santiniketan (after the name of the house). Santiniketan became a spiritual centre where people from all religions were invited to join for meditation and prayers. He founded an ashram here in 1863 and became the initiator of the Brahmo Samaj.
