via Vietnam Net, 09 August 2021: A story about a Cham tower located on top of a mountain in Binh Dinh province.
Hon Chuong Tower, also known as Hon Ba or Ba Chang, is on the peak of Ba Mountain, over 720 meters above sea level. The mountain is in Cat Tai Commune in Phu Cat District, around 50 kilometers from Quy Nhon, a key city in Binh Dinh.
In the late 19th century and early 20th century, Henri Parmentier, a French researcher and architecture, conducted surveys and collected statistics to make a map of nearly all Champa towers. However, for certain unknown reasons, he missed Hon Chuong Tower.
Decades later, Vietnamese scholars undertook research on Champa towers and other cultural relics in the area. Yet, again, they failed to trace Hon Chuong Tower, perhaps because of its remote location.
