My Son
The sacred valley of the Cham Kingdom and the most important Hindu sanctuary in Southeast Asia after Angkor Wat — My Son (4th-13th century CE; over 70 brick towers built across 9 centuries) was the religious capital of the Cham civilisation that dominated central Vietnam for a millennium; today approximately 20 towers survive in varying states of preservation; the combination of dense jungle, brick-red towers, and the silence of a valley surrounded by forested hills makes My Son one of the most moving heritage sites in Asia, despite the devastation of the Vietnam War.
