It's impossible not to appreciate the wonderful architectural design of Hang Dau Water Tower, a notable historic tower that has been able to stand the test of time.
You'll be spoiled for sightseeing choice when visiting Ba Dinh. Hang Dau Water Tower is an ideal place to kick off here, but there are lots of other fine spots to explore. Hoan Kiem Lake, Thang Long Water Puppet Theatre, and Temple of Literature are not far from the historic construction and will top off your day nicely.
