Champa asking China for reinforcements to attack Dai Viet. Much of Champa was dissolved after the 1471 Cham–Vietnamese War; Vijaya was complete destroyed; while other southern principalities had a protectorate-like status within Dai Viet. Architecture Vijaya's architecture distinguishes it from other Champa centers, because it used a combination of stone and brick elements, while most other Cham structures only used bricks. This suggests some influence from Cambodian Angkor. It also points to the relative abundance of labour in Vijaya compared to other Champa centres of powers, because processing stones for construction was more labour-intensive than the production of bricks. Vijaya's style of architecture seems to have been dominant throughout Champa for some time, given the later classification of the architecture from the period between the 12th and 14th centuries as the 'Binh Dinh style'. Remains A relatively large number of towers built in Vijaya have been preserved in Bình Định Province. They include the ruins of the citadel: Cánh Tiên tower and several temple towers. The Dương Long towers are among Southeast Asia's tallest Hinduist buildings. Capital of Tây Sơn dynasty The ruins of Tây Sơn era Hoang De citadel lies within the old Champa city walls.
