Imperial Citadel of Thang Long-Hanoi (Viet Nam) The Thang Long Imperial Citadel has become the 900^th site to be inscribed on UNESCO's World Heritage List. The Citadel was built in the 11^th century by the Ly Viet Dynasty, marking the independence of the Dai Viet.

Historic monuments of Dengfeng, in the "Centre of Heaven and Earth" (China) Mount Songshang is considered to be the central sacred mountain of China. At the foot of this 1500 metre high mountain, close to the city of Dengfeng in Henan province and spread over a 40 square-kilometre circle, stand eight clusters of buildings and sites, including three Han Que gates - remains of the oldest religious edifices in China -, temples, the Zhougong Sundial Platform and the Dengfeng Observatory.

Episcopal city of Albi (France) On the banks of the Tarn river in south-west France, the old city of Albi reflects the culmination of a medieval architectural and urban ensemble. Today the Old Bridge (Pont-Vieux), the Saint-Salvi quarter and its church are testimony to its initial development (10^th -11^th centuries). Following the Albigensian Crusade against the Cathar heretics (13^th century) it became a powerful episcopal city.
