The tunnels of Củ Chi (Vietnamese: Địa đạo Củ Chi) are an immense network of connecting tunnels located in the Củ Chi District of Ho Chi Minh City (Saigon), Vietnam, and are part of a much larger network of tunnels that underlie much of the country. The Củ Chi tunnels were the location of several military campaigns during the Vietnam War, and were the Viet Cong's base of operations for the Tết Offensive in 1968.

Cao Dai Temple (also called Tay Ninh Holy See) was built in 1933 and officially inaugurated in 1955. It is a special religious work of Caodaism (Cao Dai religion), located in Hoa Thanh District, about 4km from Tay Ninh City. In the early 1920s, Caodaism was established in Southern Vietnam but had not been officially codified until 1926. It is the 3rd largest religion in Vietnam borrowing elements of Buddhism, Christianity, Taoism, Confucianism, and Islam. It is currently estimated that there are nearly 3 million followers nationwide, living in 38 provinces and cities, mainly concentrated in South Vietnam.

Black Virgin Mountain (Vietnamese: Núi Bà Đen meaning "Black Lady Mountain") is a mountain in Tây Ninh City, Vietnam. The mountain is the center of a Vietnamese myth about Bà Đen. During the Vietnam War the area around the mountain was a hot zone as the Ho Chi Minh Trail ended a few kilometers west across the Cambodian border. As such there were many battles and American and Vietnamese soldiers based in the region remember the prominent landmark.[1] After the war the mountain turned from a battleground to being famous for its beautiful temples and theme park.
