Tay Ninh town, the capital of Tay Ninh province, serves as the headquarters of one of Vietnam’s most intriguing indigenous religions, Cao Daism. The Cao Dai Great Temple at the sect’s Holy See is one of Asia's most unusual and astonishing structures. Built between 1933 and 1955, the temple is a rococo extravaganza blending the dissonant architectural motifs of a French church, a Chinese temple and an Islamic mosque.
Tay Ninh province, northwest of Ho Chi Minh City, is bordered by Cambodia on three sides. The Vam Co River flows from Cambodia through the western part of the province. The area’s dominant geographic feature is Nui Ba Den (Black Lady Mountain), which towers above the surrounding plains.
