After the heavenly departure of Sant Baba Harnam Singh Ji in 1989, the Sangat felt a deep responsibility to continue his spiritual mission. With dedication and unity, the foundation stone (Neeh Pathar) of Gurdwara Dera Harnamsar Nanaksar Zira was laid in 1990.

Through the tireless seva of the Sangat, who worked day and night with devotion and faith, the beautiful Gurdwara building was completed. The present structure, as seen in the photo gallery, stands as a symbol of unity, sacrifice, and unwavering devotion.

Every year, from 3rd November to 13th November, the Barsi Samagam of Sant Baba Harnam Singh Ji is celebrated with great respect and spiritual enthusiasm. Devotees, Ragis, and Kirtani Jathas from different cities and distant regions gather to participate in ten continuous days of Gurbani Kirtan. Akhand Paths are organized, and the entire event is conducted with great honor and devotion.

Following the Barsi Samagam, the Parkash Purab (birth anniversary) of Guru Nanak Dev Ji is also celebrated with great joy and reverence.

In addition to annual events, Sangrand, Puranmashi, and Masya are observed every month with spiritual gatherings and continuous Guru Ka Langar. The Sangat performs seva wholeheartedly, and large numbers of devotees attend regularly.

Sant Hari Singh Ji personally meets devotees, listens to their concerns, shares spiritual guidance, blesses them, and distributes Prashad. The Gurdwara continues to serve as a center of faith, seva, and spiritual upliftment for the community.
