Gurdwara Mata Sundri Sahib
Gurdwara Mata Sundari Sahib ji is associated with Mata Sundari ji and Mata Sahib Devan ji. They had been residing in Kucha Dilwali Singhan until 1725 when, subsequent to the execution of Mata Sundari's adopted son Ajit Singh in June 1725, they thought it safer to move out of Delhi, but after about two years stay at Mathura they came back to Delhi, and made their abode in a house outside Turkman Gate about two kilometers out of Chandni Chowk. This house came to be called Mata Sundari Ki Haveli.
Mata Sundri expired in 1747 A.D. while Mata Sahib Kaur died a year or two later. The samadhis of both of them were constructed on the river bank where Gurdwara Bala Sahib stands today. After the death of Mata Sahib Kaur the Guru's weapons were preserved by Bhai Jiwan Singh and his descendants in their house in 'Chitli Kabar Mohalla' of Matya Bazar. Some of these weapons are now kept in Gurdwara Mata Sundri. The martyrdom day of Guru Gobind Singh's sons is observed here every year by Sikhs of Delhi with great devotion and dedication.
The Gurdwara at the back of Irwin Hospital has now a palatial three-storey building with the facade having bay windows on the first floor and decorative domed kiosks on roof top. Death anniversary of Guru Gobind Singh's sons falling in December is observed here on a big scale.
