Located approximately 100 kilometres northwest of Ho Chi Minh City, the Cao Dai Holy See is the principal centre of Caodaism, a Vietnamese religion founded in 1926. Its distinctive architecture blends elements associated with Buddhism, Taoism, Confucianism and Christianity, creating one of the country’s most visually striking religious landmarks.

The complex is instantly recognisable for its colourful façade, twin towers, decorative columns and intricate dragon mosaics. Inside the main sanctuary, rows of pillars and a vaulted ceiling frame the Divine Eye, the sacred symbol of Caodaism representing the supreme deity. The combination of vivid colours, religious symbolism and elaborate ornamentation reflects the faith’s philosophy of bringing together different spiritual traditions.

Beyond its architecture, the Holy See remains an active place of worship and an important part of Tay Ninh’s cultural identity. Daily ceremonies are held at set times, with the noon service particularly popular among visitors wishing to observe the rituals, music and traditional attire of worshippers. Visitors should dress modestly, remove their shoes when entering designated areas and remain respectful during ceremonies.
