Gurudwara Bangla Sahib is one of the most prominent Sikh gurdwara, or Sikh house of worship, in Delhi, India, and known for its association with the eighth Sikh Guru, Guru Har Krishan, as well as the holy river inside its complex, known as the "Sarovar." It was first built as a small shrine by Sikh General Sardar Baghel Singh in 1783, on the bungalow donated by king Raja Jai Singh of Amer, who supervised the construction of nine Sikh shrines in Delhi in the same year, during the reign of Mughal Emperor, Shah Alam II.
