At the foot of Mount Cangshan, the Hongsheng Monastery Pagoda rises forty-three point eight seven meters into the Yunnan sky. Built during the Dali Kingdom between the tenth and thirteenth centuries, this sixteen-tier square brick tower is a solitary survivor. The grand royal monastery that once surrounded it, known as the Wangshe Monastery, vanished by the early Ming Dynasty. Later, scholars studied in an academy built on its ruins, and Qing Dynasty worshippers built the Laojun Temple nearby.

The structure stands on a six-meter-square stone base. Its lower three meters consist of heavy stone blocks, providing a solid anchor against regional earthquakes. Above this base, sixteen levels of dense brick eaves overlap, tapering gently from the eleventh story upward to form a soft parabolic silhouette. On the west face, three meters above the ground, a stone-framed doorway without steps features a cool marble relief of a Bodhisattva. Inside, the hollow tower reveals a complex engineering system. Twenty wooden beams crisscross in a ten-tier grid to support the upper brick walls. A central wooden pillar once stood in the lower chamber, though thieves stole it during the Ming Dynasty, and its 1545 replacement by prefect Li Yuanyang was stolen again in the late twentieth century.

At the very top, a three-meter copper spire catches the mountain light. Wind chimes hang from an octagonal canopy, suspended above an inverted bowl, a lotus pedestal, and seven wheel discs. During a major restoration in 1981, archaeologists climbed to this spire and recovered over five hundred sacred objects. They found a gilt bronze statue of the Vairocana Buddha, miniature pagoda models, scriptures, and one hundred and fifty-six sea shells used as ancient currency. Today, the pagoda tilts slightly to the east, holding the physical memory of medieval builders, imperial worshippers, and the quiet passage of a thousand years.
