Truong Tien bridge crossing the Perfume River in Hue. Orchid flowers are said to fall in the river during the autumn giving the water a light fragrance. The bridge was constructed in 1899 by Gustave Eiffel, the French engineer/architecture better known for building that tower in Paris. The Citadel flag tower, at 37 m the largest in Vietnam, is shown at the upper left. Love the houseboat cruising under the bridge. [NOTE: I am not convinced that the water in this section of the river smells like orchids during the autumn].
