Archaeological Survey of India – Associated with the name of King Ballal Sena of the Sena dynasty, this extensive mound was excavated by the Archaeological Survey of India between 1982-83 and 1988-89. The excavation revealed a stupendous brick structure in an extensive yard, enclosed on all sides by walls. Stucco heads, terracotta human and animal figurines, copper utensils, and other objects, such as iron nails, were found during the excavation. The upper remains are datable to the 12th century AD, built over earlier structures from the 8th-9th century AD. There are traces of renovation and superimposition of structures, with later activities revealing the remains of a temple complex datable to the 12th century AD.

Bengal is sometimes called Gauḍadeśa, partly because it forms a portion of Maithila and partly because the capital of the Hindu king Rāja Lakṣmaṇa Sena was known as Gauḍa. This old capital later came to be known as Gauḍapura and gradually Māyāpur.
(CC Ādi 1.19 purport)

The celebrated ancient capital of the Sena dynasty, which was known as Gauḍadeśa or Gauḍa, was situated in what is now the modern district of Maldah. Later this capital was transferred to the ninth or central island on the western side of the Ganges at Navadvīpa, which is now known as Māyāpur and was then called Gauḍapura. Lord Caitanya appeared there, and Lord Nityānanda came there and joined Him from the district of Birbhum. They appeared on the horizon of Gauḍadeśa to spread the science of Kṛṣṇa consciousness, and it is predicted that as the sun and moon gradually move west, the movement They began five hundred years ago will come to the Western civilizations by Their mercy.
Caitanya Mahāprabhu and Nityānanda Prabhu drive away the five kinds of ignorance of the conditioned souls. In the Mahābhārata, Udyoga-parva, Forty-third Chapter, these five kinds of ignorance are described. They are (1) accepting the body to be the self, (2) making material sense gratification one’s standard of enjoyment, (3) being anxious due to material identification, (4) lamenting and (5) thinking that there is anything beyond the Absolute Truth. The teachings of Lord Caitanya eradicate these five kinds of ignorance. Whatever one sees or otherwise experiences one should know to be simply an exhibition of the Supreme Personality of Godhead’s energy. Everything is a manifestation of Kṛṣṇa.
