Built inside the complex of Do Ban citadel relics in Nhon Hau commune, An Nhon town in the 12th century. The special feature of Canh Tien tower is that the inner part of the wall columns is covered with sandstone slabs carved with twisted rope patterns. The tower is elegantly designed but dignified, the tower has 4 floors that are miniature to the top, each floor has 4 decorative corner towers, each corner has small floors, creating the shape of leaves turning smaller and smaller to create a sense of harmony. It feels like a bird's wings are flying, from the shoulder of the tower upwards, all four sides are like the wings of a fairy flying up, so it is called Canh Tien tower. The tower was built in the reign of King Che Man, so there is a legend that: this is the tower of King Che Man dedicated to Queen Paramecvari, Princess Huyen Tran, the noble Vietnamese daughter with whom he made a historical relationship. The tower was ranked as an architectural monument by the Ministry of Culture and Information in 1982.
