Gurdwara Bangla Sahib is the most prominent Sikh gurdwara, or Sikh house of worship, in Delhi. It is instantly recognisable by its stunning golden dome and tall flagpole. Gurdwara Bangla Sahib was originally a bungalow belonging to Raja Jai Singh, an Indian ruler in the seventeenth century. The eighth Sikh Guru, Guru Har Krishan resided here during his stay in Delhi. During that time, there was a smallpox and cholera epidemic, and Guru Har Krishan helped the suffering by giving aid and fresh water from the well at this house.

The Gurdwara is now a place of pilgrimage for both Sikhs and Hindus.
