The Bangkok National Museum is one of the largest museums in Southeast Asia and the primary branch of Thailand's National Museums. It displays exhibitions of Thai art and history. It occupies the former Front Palace, between Thammasat University and the National Theater, facing Sanam Luang. King Chulalongkorn opened the museum in 1874 to display his father's royal collections. The galleries showcase Neolithic-era Thai artifacts. The collection includes King Ram Khamhaeng's Inscription, placed on UNESCO's Memory of the World Programme in 2003. The museum shows Thai antiquities from Dvaravati, Srivijaya, Sukhothai, and Ayutthaya, as well as Indian Gandhara, Chinese Tang, Vietnamese Cham, Indonesian Java, and Cambodian Khmer arts.
