With regard to the Moidams, built by the Tai-Ahom State and included as a UNESCO World Heritage Site, which of the following statements is/are correct ? 1. They served as military forts. 2. They were recreation centres of royals and nobles. 3. They were burial ground of royals and nobles. 4. They were battle drill centres of royals and nobles.

Moidams (Maidams) of the Ahom dynasty in Charaideo, Assam, were inscribed as a UNESCO World Heritage Site in July 2024. They are mound-burial systems where the Ahom kings and members of the royal family were buried along with their belongings. They served as burial grounds, not as military forts, recreation centres, or battle drill centres. The Charaideo Moidams are often called the 'Pyramids of Assam' due to their pyramidal mound structures. Hence only Statement 3 is correct.
