Mundeshwari Devi Temple is an ancient temple located at Kaura in the Kaimur district of Bihar.
The temple is dedicated to Lord Shiva and Goddess Shakthi. This is one of the oldest functional Hindu Temples in Bihar. One of the inscriptions in the temple dates back the temple to 635 AD.
But there are other conclusions like the temple exists from 105 AD itself.
