A very peaceful historical site with many monuments and beautiful views. There weren’t many tourists, so we were able to fully enjoy the area, explore all the buildings, and even visit the underground bunker. Definitely worth seeing for anyone interested in history and unique architecture, offering both a quiet atmosphere and fascinating sights that make it a memorable experience.

Cost is VND 100 per adult, kids under 16 free, Vietnamese students and pensioners VND50. A lively city escape to the counties past. A strong sense of Vietnam’s long history — layers of human activity, governance, architecture and culture through many dynasties.
A mixture of grandeur and ruins: some parts restored or reconstructed, others touching only as foundations. That contrast can be quite powerful.
Moments of reflection: war scars, the evolution of the site from royal court to colonial impacts, to modern city.
Photo opportunities: gates, walls, stone carvings, the Flag Tower, views, especially under good light

Huge place. Parts of the gardens are beautiful but there was a lot of hoarding up around a lot of buildings and the areas that describe the history are very good but your left wanting. So much more history could be told in the spaces they have.
