Mustang: Once a symbol of power and devotion, the majestic Lomanthang Palace in Upper Mustang now stands in quiet decline, surrounded by crumbling mud walls and echoing the memories of a once-thriving kingdom.

Known locally as Tassi Dhyafel, meaning “Lucky Palace,” the 15th-century structure was built by King Amepal and protected by a nine-meter-high, 563-meter-long defensive wall. Today, the ancient palace, once guarded by royal soldiers, seems to be watched only by a lone dog, locals say.

Though the palace is rich in history, architecture, and culture, locals complain of a lack of state support for preservation. The once-bustling fortified settlement, which housed up to 160 families and royal ministries, has gradually emptied as newer homes sprout outside the wall — a trend that accelerated after Nepal became a republic.

“This palace is not just a building; it’s our identity,” said Tasinharbu Gurung, Chairman of Lomanthang Rural Municipality. “If preserved properly, it could uplift the local economy through tourism. But neglect threatens its legacy.”

Despite the palace’s status as a site of historical and archaeological significance, locals say neither the government nor conservation agencies have shown serious interest in restoration or promotion. They worry that the depopulation and isolation of the area may lead to irreversible damage.

Lomanthang’s heritage is deeply tied to Tibetan and Buddhist culture. Its monasteries - Jhampa, Thubchen, Chode, and Chopla — feature centuries-old murals, scriptures, and artwork. Located at 3,880 meters above sea level, Lomanthang is also the gateway to Upper Mustang and offers breathtaking views of Nilgiri, Dhaulagiri, and Annapurna.

The region still respects its royal lineage. The 26th King of Lomanthang, Jigmepalwar Bisht, continues to reside in the area, and locals refer to him with reverence.

Lomanthang once flourished as a trade hub between India and Tibet before geopolitical changes and the collapse of the salt trade route weakened its economy. Nevertheless, its potential as a world-class cultural and adventure tourism destination remains untapped.

Chairman Gurung added that “Sija Jhong,” a vast cave complex nearby with at least 60 rooms carved over 2,000 years ago, draws almost every visitor. “Yet we lack infrastructure and government help to preserve and promote our heritage,” he said.

As calls grow louder for conservation and responsible tourism development, Lomanthang stands as a reminder of Nepal’s hidden histories — majestic, meaningful, and at risk of being forgotten.
