History

Longwetu Mountain City Ruins (垅圩图山城址) date back to 650 AD when Xinuoluo built the first capital of the Nanzhao Kingdom here. The site’s name has appeared in historical records since the late Nanzhao period. Ancient texts describe impressive city walls once standing up to 9 meters high, though no visible remains were left by modern times. Archaeological excavations since the 1950s have uncovered building materials and foundations, confirming its importance as an early capital. Visitors can appreciate this rich history through the ruins and artifacts found on the mountain.
