Gurdwara 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, and the pool inside its complex, known as the "Sarovar." It was first built as a small temple 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.
