Gurdwara Shaheedsar Dhidha Sahib is located in Sahibzada Ajit Singh Nagar (Mohali), Punjab, India. It marks the place where Baba Banda Singh Bahadur stayed during the battle of Chappar Chiri and also cremated here the brave warriors who lost their lives in the battlefield.
It was in 1925 that Sant Baba Atar SIngh Ji said that in the coming years that there will be a wonderful Gurdwara at this place. Finally in 1985 under Sant Baba Dalbir Singh the development work started and a Gurdwara was built at this place.
