Manikchari Mung Rajbari, the ancient abode of the historic Mung Raja, is located in Manikchari upazila, 36 km southwest of Khagrachari district town. The Hmong are one of the various ethnic groups living in the hilly areas of the Chittagong Hill Tracts for centuries. In ancient times, this ethnic group had a separate autonomous monarchy known as the Mong dynasty. In 1796, King Kangjoy married a princess of the Tripura dynasty at Mahamuni in Manikachari upazila of Khagrachari. Later he came to Manikchari from Sitakunda with 500 Tripura families and established Manikchari Mong Rajbari for the residence of the royal family members. This is how the journey of the Mong royal family began in Manikchari from the time of Kangjoy. When King Kangjoy of Tripura died in 1826, his son Kyojai Sen succeeded to the vacant throne under the tutelage of his uncle Lathyanya at the age of 7. Later, Kyozhai Sen was appointed as the head of the Mong Circle by the British government. After Kyozhai Sen, other descendants of the dynasty continued to rule the kingdom, being appointed as chiefs of the Mong circle. He was awarded the title of Honorary Colonel Rank for his special contribution to the Liberation War of Mong Pru Sin, the seventh king of the Mong Dynasty.
A Buddha statue of Vishwa Shanti Mahamuni Raja Buddha Chaitya has been installed near Manikchari Mong Rajbari.
