The complex consists 12 individual and grouped relics of six special national relic zones in Quang Ninh province, Bac Giang province (now Bac Ninh), and Hai Dương province (now Hai Phong city). Covering 525 hectares on the Yen Tu mountain range in northeastern Vietnam, the complex boasts ancient architectural works and birthplace ofthe Truc Lam Zen sect, founded by King-Monk Tran Nhan Tong in the 13th century.
The beauty of Yen Tu lies in its superb mountains where ancient temples and stupas quietly blend with serene natural landscapes. There are hundreds of hermitages, stupas of Zen masters, and Buddhist steles. Yen Tu mountain has a rich ecosystem of fauna and flora. In 2012, Yen Tu was designated a special national historical and scenic relic site. Every year, it welcomes millions of pilgrims.
“This is my first visit to Yen Tu. I climbed up the mountain instead of taking the cable car. This is one of the most beautiful and sacred places I’ve ever been to,” a visitor said.
“This place is majestic and magnificent. This sacred place offers a sense of inner peace us.”

The Yen Tu-Vinh Nghiem-Con Son, Kiep Bac complex comprises three closely interconnected elements that reflect the Truc Lam Zen Buddhist sect’s development, from enlightment in Yen Tu to dissemination in Vinh Nghiem, and revival in Con Son-Kiep Bac. The system illustrates the connection between the state, religion, and communities in a specific historical period.
Vinh Nghiem pagoda preserves 3,000 woodblocks of ancient Truc Lam Buddhist scriptures, which were recognized by UNESCO as a World Documentary Heritage in 2012. These woodblocks are the “source code” of Truc Lam Zen, a pure philosophy of Vietnamese Buddhism.
Venerable Thich Thanh Vinh, Deputy Abbot of Vinh Nghiem pagoda, said: “Vinh Nghiem pagoda plays two roles: as a center for teaching Truc Lam Buddhism and as a center for carving, publishing, and distributing scriptures. We preserve the woodblocks by translating their contents. The management board divides the woodblocks into groups, and the ones deemed most relevant to modern society are prioritized for translation. Since 2015, three high-value sets have been translated.”
Vinh Nghiem pagoda, with its solemn Trinity Gate, ceremonial hall, incense hall, main shrine, and iconic eight-roof bell tower, is a masterpiece of Ly and Tran dynasty architecture. It was once home to all three Truc Lam progenitors and served as the headquarters of the Truc Lam Buddhist Sangha and Vietnam’s first monastic training school.
While Vinh Nghiem is the foundational center of the Truc Lam sect, Con Son-Kiep Bac is where the Truc Lam sect came to life. Incorporating the cultural values of multiple regions, Con Son-Kiep Bac is a treasure of tangible and intangible heritages.

Pham Thi Hue, Deputy Head of the Tourism and Services Office of the Con Son-Kiep Bac Relics Management Board, says Kiep Bac temple is deeply revered by the people and symbolizes the harmonious blend of faith, religion, and public sentiment. “Kiep Bac Temple preserves a wealth of tangible and intangible cultural values, and maintains many traditional customs, such as rubbing elephant leg bones to pray for health, and the ‘entering through the father’s gate, exiting through the mother’s gate’ ritual,” she added.
Stretching from the sacred peak of Yen Tu to Vinh Nghiem pagoda and the Con Son–Kiep Bac relics, this heritage route represents a continuous historical flow from past to present. With its recent recognition by UNESCO as a World Cultural Heritage Site, the complex has gained international acclaim and is poised to create new cultural and economic values as Vietnam deepens its global integration.
