From Hoi An I was able to catch a bus straight to Hue, and almost literally from hotel to hotel.

Of all the places I had wanted to go in Vietnam before I ever thought I would actually get the chance,
Hue City was at the top of the list for several reasons. First, it was the site of some of the heaviest most intense fighting of the
Tet Offensive of 1968, it was also the imperial capital of Vietnam during the Nguyen Dynastic period, and the central portion of the city consists of a walled fortress city surrounded by moats and the Perfume River.
I've never been a particularly big fan of architecture, or Asian architecture, but it is nevertheless interesting to visit the grounds of the Imperial Palace. It is as one might imagine, the primary tourist destination in Hue. And it's pretty hard to miss, it's right in the center of town. My hotel was only a few blocks away so I walked over the bridge on the
Perfume and through the gate. Within the outer walls is more Hue City, and a smaller Palace Compound.
The main entrance gate.
Various buildings just inside the main entrance all of them on the main courtyard. Originally the columns would have supported covered roofs so that you could walk between the buildings without getting rained on.
Beyond the first courtyard many of the buildings were in various states of restoration, at times you could smell the heavy paint fumes.
Inside the Palace behind all the audience halls were a number of residences for the royal family. As recently as the
French Indochina War the Emperor
Bao Dai lived here and had tennis courts installed.
These dragon banisters flanked almost every stairway in the Palace. At one point if I recall correctly, they were painted.
The Citadel was the site of some of the most severe and brutal house to house fighting of the battle for Hue, and some of the damage is still visible on the inside face of the walls.
For a while the U.S. forces attempted to retake the Citadel without the use of heavy weapons in order to prevent it's destruction. The occupying NLF forces proved to be so tenacious however that the U.S. Air Force was called in to napalm pockets of resistance. Naturally, some other stuff got burned, like this building above, still in ruins.

I spent the better part of three hours wandering around the palace grounds, mostly by myself. I'm not sure if the lack of people was due to the heat, which was intense at midday, or because it was off-season for tourists. Either way it was nice to see it by myself without the bother of other people. Eventually I left through the North-ish gate on the opposite side from where I entered. I wanted to go to the Northernmost corner of the Citadel where the fighting had been fiercest at the beginning of the battle in 1968. As you can see from the map below, there are lots of lagoons inside the walls, these were mostly choked with weeds. I drew a line on the map tracing my route out of the Palace grounds. When I got to Le Trung Dinh and Dinh Tien Hoang I encountered a military gate and checkpoint past which I could not pass and was enthusiastically reminded that I was not allowed to take pictures of the checkpoint or anything nearby.

At this point it was so damn hot I just decided to head home. I was hungry too and strangely enough a guy on a motorbike with his wife and kid offered to take me to his house for lunch. He was really nice, was an English teacher and I was a bit curious, but I felt really awkward about accepting, so I graciously didn't. Walked for almost another hour and ended up at a tiny coffee stand by the same gate I had entered. From the opposite direction I noticed something that had escaped me before: rocket damage. Also notice that there is no sidewalk through the gate which was about wide enough for a small car and a motorbike to pass.
By the time I got back to the hotel I had been in the Citadel for over four hours and was a little bit sunburned, but totally satisfied.
