The Diamond Throne Pagoda of the Miaozhan Temple, Buddhist pagoda in Kunming, China.

The Diamond Throne Pagoda of the Miaozhan Temple stands in Guandu Ancient Town, Kunming. Its square base, 10.4 m per side and 4.7 m high, has arched gates on all four sides forming a cross-shaped passage. The central tower rises 16.05 m, flanked by four small Tibetan-style towers about 9 m tall.

The structure was built during the Ming Dynasty as part of a significant construction effort in the region. A major earthquake in the 17th century caused substantial damage, after which the site was repaired and restored over time.

Locals call it the "Chuanxin Pagoda" (Heart-Piercing Pagoda) because two roads cross inside its square base, forming a cross-shaped passage. The east and west gates are inscribed in Chinese with "Pagoda of Meritorious Virtue" and "Gate of Prolonged Life" by Zhang Mao of Poyang; the north gate bears Lantsa Sanskrit seed syllables of the five Buddha mothers, while the south gate's carving is weathered beyond reading. The square in front is a gathering place for residents and hosts folk performances and cultural exchanges.

The pagoda stands in the central square of Guandu Old Town, with the Sande Temple to its east, the Confucian and Guandi temples to its west, the Miaozhan Temple to its north and the Tuzhu Temple to the south. The cross-shaped passage through the square base lets visitors walk beneath the five towers. The ground here is former Dianchi lakebed with thick shell deposits, so the base has settled and the whole structure was jacked up 2.6 metres in 2002.

The cross-shaped passage through the square base lets two paths meet inside the pagoda, which is why locals call it the "heart-piercing pagoda". A 2.5-metre bronze relief is set into the vault above the crossing, showing a central Buddha ringed by eight others and scroll-cloud motifs at the corners.
