Chandraketugarh, located in the Ganges Delta, are a cluster of villages in the 24 Parganas district of West Bengal, about 35 kilometres (22 mi) north-east of Kolkata.

A mound at the Berachampa village (Deuliya), off the Barasat-Basirhat Road, used to be called Chandraketur Garh (fort of Chandraketu), which was later compounded as Chandraketugarh.

[2] The legend of Khana, a medieval Bengali language poet and astrologer from the 9th to 12th centuries AD (also known as Lilavati in some traditions), is closely tied to the ancient site of Chandraketugarh.

Varāhamihira, often called Mihira or Varaha, was one of the Nine Gems (Navaratna) in the court of the Indian emperor Chandragupta II 'Vikramaditya'.

However, she exceeded him in the accuracy of her predictions, and at some point, either her husband (or father-in-law) or a hired hand (or possibly Khana herself under great duress) cut off her tongue to silence her prodigious talent.

[9][10][11] Chandraketugarh is thought to be a part of the ancient kingdom Gangaridai that was first described by Ptolemy in his famous work Geographica (150 CE).

[12][1] A recent archaeological study being conducted by a team from IIT Kharagpur, believes that King Sandrocottus (mentioned by Greek explorer Megasthenes) was Chandraketu, whose fort Megasthenes visited India in the third century BCE, after Alexander's invasion of India, and gives a detailed account of what he saw in Indica.

[15] Chandraketugarh features many examples of terracotta art, displaying an unusual degree of precision and craftsmanship.

[5] A museum has been built near the site depicting largely collections of Dilip Kumar Moitey, a retired school teacher and amateur archaeologist.
