Although the leaders of Ling in Dokham have historically supported many monasteries, Ronggo Monastery has always been regarded as the most esteemed monastery of Lingtsang. This is because Ronggo Monastery was originally King Gesar’s palace, also known as the "Lion-Dragon-Tiger Palace" (Senjong Dazé). The location of the palace aligns with the descriptions in the epic of King Gesar.

In Tibetan history, the Tertön master Chögyal Lingpa is renowned as an outstanding historian. His biography includes a story about him rebuilding the old palace of Lingtsang. At that time, Tertön Chögyal Lingpa believed that rebuilding the palace was crucial for maintaining world peace, despite some ministers thinking it would be a laborious and demanding task.

Chögyal Lingpa identified the old palace at Ronggo Monastery as the "Lion-Dragon-Tiger Palace" built by King Gesar and emphasized its significance. Ultimately, the descendants of King Gesar followed Chögyal Lingpa's suggestion to rebuild the old palace. They resided there and regarded it as King Gesar's ancestral temple, preserving it and passing it down through generations.

The "King Gesar Museum" at Lingtsang Ronggo Monastery currently holds a collection of precious historical artifacts. These include valuable relics from the descendants of King Gesar's family, such as items belonging to King Zanshan. Among them are imperial fabrics and brocade offered by Ming Dynasty emperors, which have been perfectly preserved, as well as ceremonial brocade used in the monastery.

The museum also displays King Gesar's personal vajra (ritual weapon) and the invincible battle flag, both of which bear witness to the glorious history of the Lion-Dragon-Tiger Palace.
