The archaeological site 'Mahasthan' means a great place. Located at a distance of 18 km. north of Bogra town, Mahasthangarh is the oldest archaeological site of Bangladesh which is situated on the western bank of the Karatoa. The spectacular site is an imposing landmark in the region having a fortified area and its ancient ruins spread out within a semi circle of about 8 km. radius. Several isolated mounds, the local names of which are Govinda Bhita Temple, Khodai Pathar Mound, Mankalir Kunda, Parasuramer Bedi, Jiyat Kunda etc. surround the fortified city. This 3rd century B. C. archaeological site is still held by the Hindus to be of great sanctity. Every year in mid-April and every 12th year in December thousands of Hindu devotees gather here for a bathing ceremony in the river Karatoa.

A visit to the site museum at Mahasthangarh will open up a wide variety of antiquities, ranging from terracotta objects to gold ornaments and coins dug up from the site. Also noteworthy are the shrine of Shah Sultan Bulkhi Mahisawar and Gokul Medh in the neighbourhood of Mahasthangarh.
