The site of Chau Doc was long in history a territory of the Kingdom of Funan (Vietnamese: Vương quốc Phù Nam). The territory became Vietnam’s around the 17th century. The town is near the picturesque mount of Sam where the Sam Mountain Lady (Vietnamese: Bà Chúa Xứ Núi Sam) is worshipped. The Sam Mount Lady Ceremony is held every April of lunar calendar (May) every year. “Mort Chrouk”(Khmer:មាត់ជ្រូក) was the Cambodian name Vietnamized in Chau Doc.
