Bangla Sahib Gurudwara was built in the memory of the 8th Sikh Guru, Sri Harkishen Sahib. Gurdwara Bangla Sahib is one of the important historical Gurdwaras in Delhi.
The large main hall is un-elaborate except for the open central shrine, where a sculpted bronze cupola hangs over a smaller golden dome under which silk sheets are spread out and covered with flowers. This shrine is the scene of constant devotional music, whose ethereal tones are relayed throughout the entire complex.
Gurdwara has also got a trough that stores the holy water known as 'Amrit' or nectar, which when consumed is believed to cure the diseases of the sick. Gurdwara also has a sarovar or a holy pond, where people take a holy dip and pray to the Guru. Raja Jai Singh dedicated this palace in the memory of the Guru Sahib, which is today famous as Gurudwara Bangla Sahib.
