Charaideo, also known as Che-Rai-Doi, is one of the most prominent archaeological sites and a historic town in Upper Assam. The name Che-Rai-Doi means “the shining city on the hills.” It is in Assam. This place was established by the Ahoms, who entered Assam in 1228 CE. In 1253 CE, the first Ahom king, Chao Lung Siu-Ka-Phaa, officially founded Charaideo, making it the first capital of the Ahom kingdom.

Charaideo has remained a symbolic center of Ahom power in Assam. Today, it is especially famous for its numerous maidams (burial mounds), which serve as the final resting places of Ahom kings and members of the royal family. Due to their unique burial structure and historical importance, the Charaideo Maidams are often called the “Pyramids of Assam,” making them a significant heritage destination.

Recognizing its historical significance, Charaideo was officially designated as a UNESCO World Heritage Site on 26 July 2024. The destination's captivating natural beauty, artistic heritage, and rich cultural legacy continue to attract visitors from around the world. It houses many symbols of Assam’s 600-year Ahom rule, including manmade ponds, ancient royal roads, and the historic maidams, all of which narrate the proud and remarkable history of Assam.
