Gurdwara Bangla Sahib is a famous Sikh religious attraction in New Delhi. Located near Connaught Place, it has a very impressive structure with a golden dome and is renowned for its association with Guru Harkrishan – the eighth Sikh Guru. The gurdwara is also renowned for a famous pond called the 'Sarovar'; the water inside which is considered as 'Amrit' (holy water) by the Sikh community members.
Originally, the Gurdwara edifice happened to be a bungalow of Raja Jai Singh – a 17th century ruler from Amber and the structure was then called Jaisighpura Palace.
The eighth guru of the Sikh community Guru Har Krishan is believed to have resided in this very same bungalow when he visited Delhi in the year 1664. During his stay at the place, deadly diseases like smallpox and cholera were prevalent at the place and to help the diseased, he would provide fresh water from a well present in the palace complex. Gradually, the guru also contacted the disease and expired in the year 1664. Later, Raja Jai Singh constructed a tank over this well and it is the same water that's considered sacred by all the Sikh community members today. People from across the globe carry water from this tank and preserve at their homes. The water is also believed to possess medicinal properties even to this day.
This temple complex includes the following within: the sarovar, a kitchen, an art gallery, a school, Baba Baghel Singh Museum, a hospital and a library.
