Dayun Temple Jingchuan: Buddha Sarira & Tang Gold Caskets

Dayun Temple (Dayun Si) in Jingchuan County, Gansu Province, stands as a quiet but powerful testament to the intertwined histories of imperial Buddhism, the Silk Road, and Chinese craftsmanship. Unlike the crowded corridors of better-known Buddhist sites in China, Dayun Temple offers a more contemplative experience anchored by a genuine archaeological sensation: the 14 grains of Buddha’s sarira (cremation relics) and the Tang Dynasty gold and silver caskets that enshrined them. The site’s altitude of 1,050 meters places it firmly on the Loess Plateau, but without the health concerns associated with high-altitude destinations.

This guide provides a thorough examination of Dayun Temple’s history, architectural features, and practical visitor considerations, drawn from verified source data and general travel logic for the Gansu region.

Historical Significance: From Sui Patronage to Tang Transformation

Emperor Wen of Sui and the First Sarira Enshrinement

In 601 AD, Emperor Wen of Sui — the monarch credited with reunifying China and formally permitting the veneration of Buddhist relics — ordered 14 grains of the Buddha’s sarira to be sent to what was then called Daxingguo Temple in Jingchuan. This act was part of a nationwide campaign to distribute relics to key temples, reinforcing Buddhist authority under imperial rule.

The Jingchuan site was chosen partly because of its strategic location along the western approach to the Sui capital, Chang’an (modern Xi’an). The relics were buried in an underground palace, marking the site as a sacred destination for pilgrims and officials traveling the Silk Road.

The Renaming Under Empress Wu Zetian

Nearly a century later, in 690 AD, Empress Wu Zetian — China’s only female emperor — proclaimed the Dayun Sutra and ordered temples across the empire to be renamed Dayun Temple. Jingchuan’s temple was among them. Wu Zetian also commissioned a new set of multi-layered reliquary caskets: an outer stone casket, then copper, silver, and finally an inner gold casket.

These caskets were interred in 694 AD, approximately 180 years before the famous underground palace at Famen Temple was sealed. This act reinforced the site’s importance as a state-sponsored Buddhist center and showcased the Tang Dynasty’s wealth and artistry.

The caskets remain one of the most complete sets of Tang imperial reliquaries ever discovered, and their quality marks a high point in Chinese metalwork history.

The 1964 Discovery: An Archaeological Milestone

By the Ming Dynasty, a devastating flood had destroyed the temple complex and buried the relics. For centuries, the treasures lay forgotten beneath the agricultural fields of Jiajia Village.

In October 1964, local farmers leveling land accidentally struck the underground palace. The subsequent excavation revealed the five-tier casket set (stone, copper, silver, gold, and a miniature gold coffin) and the 14 grains of sarira, still intact within the innermost casket.

This discovery was quickly recognized as one of the most significant Buddhist archaeological finds in China. It was later recorded in the Encyclopedia of China and prompted international exhibitions — the caskets have traveled to Japan, the United States, and more than ten other countries as representative cultural artifacts of the Tang Dynasty.

Today, the relics are housed in the temple’s modern underground palace, which was built as part of the reconstruction of Dayun Temple in the early 2000s. Visitors can view the sarira in a controlled environment, though the original gold and silver caskets may be displayed in separate museum settings (exact current location should be confirmed locally).

Architectural Grandeur: The Modern Tang-Style Complex

Layout and Tang Revival Design

The current Dayun Temple complex was rebuilt in the early 21st century based on Tang Dynasty architectural principles. The complex includes a Mountain Gate, two Stele Pavilions, a Bell Tower, a Drum Tower, and the centerpiece — the Dayun Pagoda. The design uses wide eaves, prominent brackets, and muted earth tones that echo the grandeur of Chang’an’s monasteries.

The Dayun Pagoda: 95 Meters of History

The pagoda stands 95 meters tall, with 14 stories: 7 visible above ground and 7 hidden below, corresponding to the seven levels of the underground palace. The structural logic is symbolic — the number 14 references the 14 grains of sarira.

The upper stories are accessible via internal stairs, offering panoramic views of the Jing River valley and the surrounding loess hills. The pagoda is a concrete and masonry structure finished to resemble Tang-era brick pagodas, though it is a modern build.

The Underground Palace: Three Levels of Relics and Scripture

The underground palace is the most significant part of the temple for pilgrims and historians. It is divided into three levels:

• Level 1 features Buddhist sculptures and murals depicting stories from the sutras.
• Level 2 is the reliquary chamber, where the gold and silver caskets (originals or reproductions, depending on museum loans) and the Buddha’s sarira are displayed for public veneration. Glass cases allow close viewing.
• Level 3 contains sacred scriptures and donor records, preserved in a climate-controlled environment.

The arrangement respects the original Tang layout, where the relics were sealed in the central chamber under the pagoda base.

Location and Accessibility

Dayun Temple sits in the center of Jingchuan County, Pingliang City, eastern Gansu. Jingchuan is approximately 200 kilometers east of Lanzhou and 250 kilometers west of Xi’an. The temple is located along the Jing River, close to the main county road.

By public transport, travelers can take a bus from Pingliang city to Jingchuan County (about 1.5–2 hours). From Xi’an, direct buses or trains to Pingliang (3–4 hours by high-speed rail) are available, followed by a local bus. The exact bus station and frequency should be confirmed with local sources, as schedules change seasonally. Driving from Xi’an via the G70 and G22 expressways takes about 4 hours.

The site is flat and accessible at ground level, but the pagoda requires climbing multiple stories — this may be challenging for visitors with mobility concerns.

Who Should Visit (and Who Might Skip)

Dayun Temple is a strong choice for:

• Buddhist pilgrims seeking to venerate authenticated relics with documented imperial history.
• Art and history enthusiasts interested in Tang metalwork, Silk Road archaeology, and sarira-related religious traditions.
• Travelers exploring the Gansu Silk Road route who want to step off the main Lanzhou–Dunhuang axis and see a less-commercialized site.

The site may be less satisfying for:

• Travelers looking for grand scenery or outdoor activities — the Loess Plateau landscape is stark, not dramatic.
• Families with young children who may not engage with the static relic displays and Buddhist iconography.
• Visitors with tight schedules — Jingchuan is not a major transit hub, so a detour from Xi’an or Lanzhou requires a full day commitment.

Best Time and Duration

Late spring (May–June) and autumn (September–October) offer the most comfortable weather — mild temperatures, low rainfall, and clear skies. Summer can be hot and dusty, while winter is cold, though the site remains open. The source data suggests no specific duration, but a typical visit to the complex (grounds, pagoda climb, underground palace) takes 2–3 hours. Add 1 hour if you also plan to explore the nearby county museum.

The temple grounds are open year-round, but check locally for holidays or maintenance closures — Lunar New Year and Buddhist festival days may have reduced hours.

Photography Notes

Photography is generally allowed in the grounds and pagoda exterior, but restrictions typically apply inside the underground palace, especially near the relics and caskets, to protect the artifacts and respect devotional atmosphere. Flash photography is always prohibited in relic chambers. The pagoda’s upper levels offer good photo opportunities of the Jing River valley, especially in the golden light of late afternoon.

No drone flights are permitted over the temple complex without prior authorization from the county cultural bureau. Do not assume permission.

Safety and Altitude

Altitude 1,050 meters is not considered high-altitude. Standard travel health precautions apply: stay hydrated, use sun protection, and take breaks in summer heat. The pagoda climb involves steep stairs; visitors with vertigo or joint issues should assess their ability. There are no significant safety hazards beyond normal outdoor conditions.
