Founded in 1926 in Tay Ninh province, the Caodaism worships the Divine Eye, known as the eye of heaven and a symbol of its supreme being. It is now the third largest religion in Vietnam.
The Tay Ninh Holy See, the centre of Caodaism in Vietnam, was completed in 1947, covering an area of more than one sq.km with twelve gates.
The Tay Ninh Holy See has unique architecture that combines various religious styles - Buddhism, Christianity, Muslim, Confucianism, Hindu and more.
At the centre of the Holy See's main temple lies a sphere, the Universe Globe, with the giant Divine Eye shining out on it. The all-seeing Divine Eye represents the eye of heaven and the symbol of the religion's Supreme Being.
The Divine Eye also appears in the windows at the main temple of the Tay Ninh Holy See.
