This royal structure, which sits at the center of Hue’s Imperial Enclosure, was once reserved for exclusive use by the emperor of the Nguyen Dynasty. Only eunuchs passed through its halls, since even his most trusted servants weren’t allowed beyond the gates. Today, this historic citadel sits mostly in ruins, destroyed during several wars throughout the nation’s history. Despite some recent rebuilding efforts, travelers can easily spend a long afternoon wandering paths that crisscross the grounds, exploring portions of the foundation, now overgrown with foliage, and examining the painting, woodwork and architecture that still remains. A 10 kilometer moat surrounds what was created to resemble the Forbidden City of Beijing, and 10 gates protect these once royal grounds.
