Founded in Vietnam in the early 1920s, Cao Dai is based on the main religions of the East and West and takes as its saints characters chosen for their moral and humanist values such as Joan of Arc, Winston Churchill and the poet Nguyen Du. The temple in Da Nang (1906), the second largest in the country, is built in an attractive colonial style and houses representations of the Divine Eye, the emblem of the doctrine, as well as the founders of Islam, Christianity, Taoism, Confucianism and Buddhism.
