The Ancient Monuments and Archaeological Sites and Remains Act of 1958 now protects Lungphun Ropui as a result of the recognition. The location, which is well-known for its medieval menhirs—carved stone structures—is said to be essential to comprehending the Mizo people's cultural and historical origins. Aspects of early Mizo life, customs, and beliefs are reflected in the distinctive stone sculptures.
These unique monuments, which are located in Lianpui village, approximately 54 kilometers southeast of Champhai town, have long caught the interest of local archaeologists and historians. In 2021, the site was formally declared by a notification published in the Indian Gazette. The final notice was released on July 14th, 2025, following a site visit by ASI Director (Monuments) A.M.V. Subramanyam on July 7th.
In order to protect the property and encourage tourism, ASI intends to upgrade the site's infrastructure with new status by putting in gates, walkways, restrooms, and drinking water facilities.
The announcement was hailed by Carol VLMS Dawngkimi, Director of the Mizoram Art & Culture Department, who attributed the accomplishment to the late Shri P. Rohmingthanga, IAS (Retd.), who was instrumental in the campaign.
According to Rin Sanga, IAS (Retd.) and INTACH Mizoram Convener, efforts to protect Lungphun Ropui began in 2010. He advised officials to concentrate on other ancient sites including Dungtlang, Farkawn, and Lungphunlian, noting that the acknowledgment raises awareness of Mizoram's archaeological value on a national level.
