The palace was built by Maharaja Rameshwar Singh of Darbhanga.
It includes 11 temples to gods and goddesses and several forts and palaces.
Its Kali temple is made of ivory and white marble that resembles the Taj Mahal.
The oldest surviving Mithila painting is found in the Gasauni Ghar (the room where the family deity is kept) of the palace.
Made in 1919 on the occasion of the Maharaja's daughter's wedding, there are very few written or photographic records of the palace.
