This was the most magnificent tomb that we visited. The history surrounding Emperor number 12 is also really interesting so if yiu can go with a guide you will get a lot more out of it.
The French influence can be seen in the architecture and features the most exquisite and ornate internal decorations.
If you have time to visit only one tomb in Hue, come here, it is stunningly beautiful.
A warning, you have to climb 129 stairs to get to the top. It is a fairly easy climb however and is done in stages.
