Bahadurgarh Fort is situated on the Patiala-Chandigarh road. The fort was constructed by Nawab Saif Khan in 1658, who established the early settlement around the fort and named the town Saifabad, later on it was named to Bahadurpur. The construction of the fort could not be completed under his rule, later it was renovated and completed by a Sikh ruler Maharaja Karam Singh in 1837. The construction of the entire fort was completed in eight years and a sum of ten lakh rupees was spent on its construction. The fort covers an area of 2100 sq. kms and is enclosed within two rounded walls and a moat with the circumference of the fort being around 2 Km. The Bahadurgarh Fort is situated at an approximate of 11. 4 kms away from the center Patiala and can be reached via NH7 in under 20 mins.

The name Bahadurgarh fort was given by Maharaja Karam Singh as a tribute to the Sikh Guru Teg Bahadur who stayed here for three months and nine days before leaving for Delhi. The fort consist of a historical Gurdwara Sahib which is a Sikh temple named Gurdwara Sahib Patshai Nauvin. This Gurudwara shows off fine Sikh architecture. The gurudwara is controlled by the Shiromini Gurdwara Prabhandak Committee. People pay visit to this gurdwara on occasions of the festival of Baisakhi every year in April. A mosque is also present inside the fort's premises. It was built by Saif Khan in the year 1668. The tomb of Saif Khan is situated 300 yards away from the fort. In the memory of Saif Khan a fair is organized during the months of January and June, named as Mela Roza Sharif Nawab Saif Ali. Since 1989, the Punjab Police Commando Training School has been located within the grounds of the Fort, on paying a visit one would find sign posts at points which will guide towards various training points of the Commandos along with the existing monument and its historical sites.

The architecture of the fort portrays a blend of Muslim and Sikh cultures as it involved rulers of both community in the construction of the Fort. Prior to falling in ruins the fort had three massive walls and two huge moats, this citadel is in a dilapidated condition today. The construction of the fort was done in a way which kept it safe from enemy breaches and any other outside attacks of any kind. Bahadurgarh Fort looked impregnable to any foreign eye, the moat (a wide and deep ditch) built all around the fort is 25 feet deep and 58 feet wide, circling the fort as two circular battlements and providing a good option for a roadblock or attacking the enemies by trapping them into the moat. The distance from the outer wall to the fort is also an unbelievably massive 110 Kms, with the walls running as high as 29 feets. The Gurudwara Sahib located within its precincts shows Sikh architecture at its best. This Gurudwara hold high religious value to the Sikhs in Punjab who make it a point to visit this place during the Baisakhi festival. The Muslims come to this fort because of the religious sentiments attached to the Mosque created inside the fort by Nawab Saif Khan, who started the settlement and named it Saifabad. The majestic architecture of the splendid fort is also a work of wonderment. There are octagonal turrets around the walls, cemented courtyard, a sanctum for the holy Guru Granth Sahib, pinnacled lotus-shaped domes in rooms are a sight to behold. One can also visit Panch Bati Garden and Punjab University which are situated nearby, the latter being only a couple of Kms away.

Baisakhi, which falls in the month of April, sees huge gatherings of Sikh devotees visit the Gurudwara inside the fort and the Mela Roza Sharit Nawab Saif Ali which is organised in the months of January and June, when the followers of Saif Ali visit his tomb and enjoy the festivities.
