The city of Agroha was situated on the ancient trade route between Taxila and Mathura. And, therefore, it remained an important center of commerce and political activities till coming into existence of a new township of Hisar-e-Firoza (Hisar) of Firoz Shah Tughlag. A hoard of coins including 4 Indo Greek, one punch-marked and another 51 coins of Agrodaka were found from the site. The discovery of the coins of Agreya Janapada (Republic) during the excavations and its ancient name Agrodaka in literature are sufficient to prove it being the headquarters of a Republic. This site was excavated by C.J.Rodgers in 1888-89 and re-excavated by H.L.Srivastava in 1938-39 by Archaeological Survey of India to a depth of about 3.65 m. This site was further excavated by Shri P.K.Sharan and Shri J.S.Khatri of the Department of Archaeology & Museums, Government of Haryana in 1978-84.Archaeological excavation on this site revealed a fortified township and continuous habitation from 4th century BC to 14th century AD. Apart from the residential and community houses, made of baked bricks, the remains of a Buddhist stupa and a Hindu temple existing side by side indicated co-existence and respect of communal harmony.
Sher Bahlol was a celebrated saint and prophesied that Ghiyas-ud-din-Tughluq (1320-25 AD) would become the king of Delhi. All four sides of the tomb have arched openings.

Years ago, there lived Mustafa Kalol, who enjoyed prestigious posts in Government; he had a beautiful and brave daughter named Bua. Once in a jungle, she encountered a tiger, a poor woodcutter Hasan helped her and took her back to the palace. She fell in love with brave and handsome Hasan. Even Bua’s father reluctantly approved of their marriage. Bua’s father sent Hasan to the battle field to fight as a soldier where he died. When Bua came to know about the sad news, she went to the pond where the lovers used to meet, with Hasan’s dead body, buried him there and built a tomb in the memory of her lover. After two years, Bua passed away, and she was buried beside Hasan’s tomb.
Chronologically almost all of them were built when Mughal emperors Akbar, Jahangir and Shahjahan reigned (1594-1626 AD). They present fine examples of an antedated Pathan style of architecture, and also resemble the style of Shargi monuments of Jaunpur. Homogeneity of grandiose architecture and planning indicate that it was a family graveyard probably of the local chiefs and nobles of repute.
