From 1802 to 1945 the Nguyen emperors ruled Vietnam from Hue. They built a walled citadel on the north bank of the Perfume River, modeled in part on Beijing's Forbidden City, and laid out their tombs in the pine-covered hills upstream. Several were planned during the emperors' own lifetimes, part garden, part palace, part temple.
Much was damaged in war and restoration continues, but the Complex of Hue Monuments is a UNESCO World Heritage Site and the city still carries a certain formality. It is a food city too. Bun bo Hue, the spicy beef noodle soup, comes from here, along with dozens of small, delicate dishes once served at court.
