Janaki Janmasthali Mandir

Janaki Janmasthali Mandir or Maa Janaki Janmbhoomi Mandir or Mata Sita Mandir or Mata Janaki Mandir is a proposed grand temple of the Hindu goddess Sita in the Mithila region at a site of the Punaura Dham in the Sitamarhi district of the Tirhut division in the Bihar state of India. The comprehensive development of the grand proposed temple of Goddess Sita at Punaura Dham can provide global recognition to the Mithila region of Bihar. In Hinduism the site is considered the place where Sita was found closed in a box from a farm field while the King Janaka was ploughing the farm field. Ramayana Research Council has also proposed the construction of the Tallest Statue of Mata Sita at Raghopur Bakhri village in the Sitamarhi district, which is near the proposed site at Punauradham. There is a plan to build Janaki Dham in Sitamarhi on the lines of Ram Mandir in Ayodhya. A campus known as Janaki Dham would be built on 67 acres of land near Punauradham. The foundation stone of the Janaki Janmasthali Mandir was laid by Nitish Kumar, the Chief Minister of Bihar on 13 December 2023 at Punauradham. In 2025 the union home minister Amit Shah said that after the construction of Ram Mandir he is focusing on the construction of the proposed Mata Sita Mandir. On 8 August 2025, he laid the foundation stone for the Janaki Janmasthali Mandir redevelopment project. It is also called as Maa Janaki Temple.

The Union Home Minister Amit Shah described Mother Sita as "the embodiment of an ideal daughter, wife, mother and Rajmata", while performing the bhumi pujan and laying the foundation stone for the grand project of Janaki Janmasthali Mandir. The life story of Mother Sita will be recreated in the form of new constructions and arts dedicated to women power and "Maatri Shakti" in the premises of the temple.

Amit Shah said

"I am telling the people of Mithila that this is not just a temple but the beginning of the rise of Mithila and Bihar."
