From archaeological point of view the district of Bareilly is very rich. The extensive remains of Ahichchhatra, the Capital town of Northern Panchala have been discovered near Ramnagar village of Aonla Tehsil in the district. It was during the first excavations at Ahichchhatra (1940–44) that the painted grey ware, associated with the advent of the Aryans in the Ganges–Yamuna Valley, was recognised for the first time in the earliest levels of the site. Nearly five thousand coins belonging to periods earlier than that of Guptas have been yielded from Ahichchhatra. It has also been one of the richest sites in India from the point of view of the total yield of terracotta. Some of the masterpieces of Indian terracotta art are from Ahichchhatra. In fact the classification made of the terracotta human figurines from Ahichchhatra on grounds of style and to some extent stratigraphy became a model for determining the stratigraphy of subsequent excavations at other sites in the Ganges Valley. On the basis of the existing material, the archaeology of the region helps us to get an idea of the cultural sequence from the beginning of the 2nd millennium BC up to the 11th century AD. Some ancient mounds in the district have also been discovered by the Deptt. of Ancient History and culture, Rohilkhand University, at Tihar-Khera (Fatehganj West), Pachaumi, Rahtuia, Kadarganj and Sainthal. Apart from this, artefacts of painted grey ware culture of the Iron Age have also been discovered near the city.
