Just north of Nha Trang, on a hill overlooking the mouth of the Cai River, these brick and stone temples were built by the Cham people from the 7th to 12th centuries. (The Cham are an ethnic group that today live mostly in central Cambodia and southern Vietnam.) The complex is named for Yang Ino Po Nagar, the patron goddess of a clan that ruled over the southern portion of the Cham kingdom. The most impressive of the remaining four temples (there were originally seven) is also dedicated to the goddess: the 9th-century, 28-meter-high (92-foot-high) North Tower with its soaring vaulted ceiling. The temples are still used to this day by Buddhist worshippers.
