The site of Go Thap is located in Communes of My Hoa and Tan Kieu, Thap Muoi District, 43km from Cao Lanh Town. Go Thap Archaeological Area is well known for 5 main relics: Thap Muoi Hill, Co Tu Tower, Binh Kieu Grave, Minh Su Temple, and Ba Chua Xu Temple. Relics in this area bear great cultural and historical value.
Co Tu Tower is 100m north of Thap Muoi Hill. It was built during the Thieu Tri period (1841-1842) and was formerly known as the Temple of Chan Lap. Behind this temple is the Dong Thap Muoi military base, which was under the command of Doc Binh Kieu, one of the leaders of the resistance against French troops. More than 2000 years ago, Thap Muoi Hill was a residential area. Archaeologists have discovered a number of antiques in this area, especially artifacts belonging to the Oc-Eo civilization. During both National Resistance Movements against the French Troops and the US Army, the military base supported liberation organizations and other resistance activities.
With its historical and cultural value, the Ministry of Culture and Information has nationally recognized Go Thap as a cultural vestige. It is expected to be developed into an interesting tourist area of the Dong Thap region.
