A nice UNESCO cover from Vietnam, featuring a miniature sheet issued in 2018 celebrating the Citadel of the Ho dinasty.
Inscribed as an universal outstanding value site since 2011, the 14th. century Ho Dinasty Citadel, built according to the feng shui principles, testifies to the flowering of neo-Confucianism in late 14th. century Viet Nam and its spread to other parts of east Asia. According to these principles it was sited in a landscape of great scenic beauty between the Ma and Buoi rivers. The citadel buildings represente an outstanding exemple of a new style of south-east Asian imperial city.
