- Charaideo Maidam, also spelled Moidam, located in eastern Assam, has been included in the UNESCO World Heritage Site list under the category of cultural property.
- Similar to the Egyptian pyramids, the maidams are earthen burial mounds of members of the Ahom royal family, whose 600-year rule came to an end due to British occupation of the region.
- Charaideo Maidam is the first site in the Northeast in the category of cultural property and the 43rd site in India to be recognised as a World Heritage Site.
- Assam has two other such sites in the natural category – Kaziranga National Park and Manas National Park, both upgraded to tiger reserves.
- Apart from the mortal remains of the Ahom rulers, their belongings are also kept in maidams.
- After the 18th century, the Ahoms adopted the Hindu method of cremation and started burying the bones and ashes after cremation in a Maidam at Charaideo.
