Gurdwara Bangla Sahib is the most prominent Sikh gurdwara in Delhi, which is known for its association with the eighth Sikh Guru, Guru Harkrishan. Originally this place was the haveli of Mirza Raja Jai Singh, who was an important military leader of Mughal emperor Aurangzeb. Hence, the name Bangla Sahib. Its original name was Jaisinghpura Palace.

Guru Har Krishan resided here during his stay in Delhi in 1664. During that time, there was a smallpox and cholera epidemic, and legend has it that Guru Harkrishan helped the people by giving aid and fresh water from the well at this house. Soon he too contracted the illness and eventually died in 1664. The gurdwara and its sarovar are now a place of great reverence for Sikhs and a place for special congregation on the birth anniversary of Guru Har Krishan.

The grounds include the temple, a kitchen, a holy pond, a school and an art gallery as well. Like all gurdwaras, the concept of langar is also practised and everyone, regardless of their race or religion can partake of meals at the langar hall. The langar is prepared by gursikhs who work there and also by volunteers who like to help out, or do seva.

The complex also houses a higher secondary school, the Baba Baghel Singh Museum, a library and a hospital. A new Yatri Niwas, and a multi-level parking space are new additions to this sprawling complex.

The Bangla Sahib Gurdwara can be visited every day from morning to late night. Usually Sikhs and non-Sikhs are expected to be appropriately attired as befitting the dignity of the holy shrine. Women and men must cover their head before entering the gurdwara premises and remove their shoes.

The art gallery located in the basement of the gurdwara is also very popular with visitors. Those with a keen interest in paintings can visit this gallery which depicts historical events connected with Sikh history. It is named after the Sikh general Sardar Bhagel Singh who supervised the construction of nine Sikh shrines in Delhi in 1783, during the time of Shah Alam II.

Visit to this sacred place is amust for its very enriching experience. One can feel the devotion, faith, belief and hospitality of the Sikh community and spend some tranquil moments to connect with the Supreme entity.
