Lahar is a town and a Nagar Panchayat in Bhind district in the Indian state of Madhya Pradesh.
The history of Lahar can be traced back to the Mahabharat era. It is said that the famous Lakchhagrih, (a palace built up of Lakh[clarification needed], which is a highly inflammable material), was built by the Kauravas for Pandavas at the end of their exile. As the legend goes, Kaurav wanted to kill Pandavas by burning them inside the Lakchhagrih. One can still find the pieces of charred lakh in the outskirts of town.
