I was watching a BBC programme on the Tet Offensive of 1968, part of a series on 20th century battles. The struggle at Hué was discussed. As soon as I saw the location camera work I thought it looked like a bastioned trace. I did some research, mainly Wikipedia, and found this:
|This looks like the architect's site plan|
Hué occupies a central location in Vietnam. It was started in 1804, on a greenfield site. It was chosen to be the site of the new Imperial Palace.
A substantial town has grown up around the Imperial site, there are ten gates from the fortress, over the moat to the city.
|A gate over the moat. Substantial damage was caused by bombing and shelling during the fighting, much of which has been repaired.|
