Famous for its golden dome, white marble façade, and the holy Sarovar (pond) within its complex, Gurdwara Bangla Sahib in New Delhi is one of the most prominent Sikh houses of worship, associated with the 8th Sikh Guru, Guru Har Krishan, who stayed here in 1664 and served the sick during a smallpox epidemic. It is believed to have healing properties; visitors often take a sip of its water.
