Situated at a distance of about 175 km from Panipat, the city of Hisar holds a prominent position in history as it was here that the first evidence of the presence of man was discovered with the excavation of pre-Harappan settlements Agroha, Banawali and Kunal. When in Hisar, tourists should visit the fascinating archaeological site of Agroha, situated 22 km from the city.

Regular excavations of the site revealed that there was a fortified township at the place and people lived here from 4th century BC to 14th century AD. The excavations revealed residential and community houses built of baked bricks along with the remains of a Buddhist stupa and a Hindu temple. It is believed that the site of Agroha served as the capital of Maharaja Agrasena of the Agrawal community. Another attraction is the Firoz Shah Palace Complex, which was built by Firoz Shah Tughlaq (1351-1388 AD) in 1354 AD. The palace complex has an open courtyard surrounded by multi-story structures. The western wall of the palace has a passage with steps that lead to the terrace. The palace complex also houses underground apartments, the Diwan-e-Aam, the Gujri Mahal and the popular Lat ki Masjid.

Tourists can also head to the Blue Bird Lake on the outskirts of Hisar. The wetland is home to resident and migratory birds and makes for a great picnic spot. Tourists can hire boats and enjoy bird watching. In close proximity lies the Deer Park, which is home to black bucks, spotted deer and sambar deer.

The city of Hisar was founded by the Muslim ruler, Firozshah Tughlaq, in 1354 AD. The name 'Hisar' comes from an Arabic word, meaning fort. Initially, the place was called 'Hisar Firoza (also Hisar-e-Firoza) or in other words, the fort of Firoz.
