Gurudwara Bangla Sahib is the most prominent Sikh Gurdwara, or Sikh house of worship, in Delhi, known for its association with the eighth Sikh Guru, Guru Har Krishan Sahib ji, and the pond inside its complex, known as the "Sarovar", whose water is considered holy by Sikhs and is known as "Amrit". It was built by Sikh General, Sardar Bhagel Singh in 1783, who supervised the construction of nine Sikh shrines in Delhi in the same year, during the reign of Mughal Emperor, Shah Alam II.
It is situated in the Connaught Place, New Delhi area and is instantly recognisable by its stunning golden dome and tall flagpole, Nishan Sahib.
Gurdwara Bangla Sahib was originally a bungalow belonging to Raja Jai Singh, an Indian ruler in the seventeenth century, and was known as Jaisinghpura Palace.
The eighth Sikh Guru, Guru Har Krishan Sahib ji resided here during his stay in Delhi in 1664. During that time, there was a smallpox and cholera epidemic, and Guru Har Krishan Sahib ji helped the suffering by giving aid and fresh water from the well at this house. Soon he too contracted the illness and eventually died on March 30, 1664. A small tank was later constructed by Raja Jai Singh over the well, its water is now revered as having healing properties and is taken by Sikhs throughout the world back to their homes.
The Gurdwara and its Sarovar are now a place of pilgrimage for both Sikhs and Hindus, and a place for special congregation on birth anniversary of Guru Har Krishan Sahib ji and death anniversary of Maharaja Ranjit Singh.
The grounds include the temple, a kitchen, a large pond, a school and an art gallery. As with all Sikh Gurdwaras, the concept of langar is practiced, and all people, regardless of race or religion may eat in the Gurdwara kitchen (langar hall). The food is prepared by gurusikhs who work there or volunteers who like to help out. At the Gurdwara, visitors are reminded to cover their hair and not to wear shoes. Head scarves and a shoe-minding service can be found inside the compound and are available free of charge. Anyone can also volunteer to help keep the shoes in the shoe-minding room. The complex also houses a higher secondary school, Baba Baghel Singh Museum, a library and a hospital.
