Mariamman Hindu Temple, Ho Chi Minh City
This small Hindu temple is frequented by both Saigon's tiny Hindu population along with resident Vietnamese. It was built in the late 19th century by traders from Tamil Nadu and is dedicated to the Hindu Goddess Mariamman. After 1975 the Vietnamese government converted it into a factory for making joss sticks, but it's now used solely for worship. The temple is only a short walk from the Ben Thanh Central Market so is certainly worth a look in.
