The collection of Champa stone sculptures which is displayed in the outdoor exhibition area of the Vietnam National Museum of History is dated back to the 3rd-14th centuries AD. It is composed of two types: objects with inscriptions and sculptures. The first type includes steles, stone columns and door lintels, and the second includes sacred animals and tower decorative reliefs, such as Linga–Yoni and Nagar serpents. The inscriptions indicate that the kings of Champa paid special attention and contributed a great deal of their property, land and effort to constructing temples and producing worship sculptures, gods and Bodhisattva statues. They are precious and valuable data for the study of the culture and history of Champa, especially the Vo Canh stele that was recognized as a National Treasure in 2010.
