Hue is famous for its Imperial Citadel, as well for Royal tombs of Nguyen dynasty who ruled Vietnam (under French blessing) from 1802-1945. There're some 7-8 tomb sites scattered around the city southwestern suburbs.
Tomb of Khai Dinh, who was the penultimate Emperor, is the most impressive and ornate one, yet with some kitschy details.
It's elevated from the street level, reaching it through a Chinese style gate via 2 stairways. On the way up to the Mausoleum you pass ornate stone guards on both sides, as well few smaller temples.
The main Mausoleum is a mix of east (Viet and Chinese) and west (French) architecture, which leaves a mixed impression of beauty and kitsch. Interiors are similar - lavishly decorated with mosaics of ceramics, glass, silver,....
