One Pillar Pagoda
It takes about five minutes to see, but the One Pillar Pagoda's odd, elegant design — a wooden temple balanced on a single stone column rising out of a lotus pond — makes it one of Hanoi's most recognisable sights.
The story behind it
Legend says the pagoda was built in 1049 by Emperor Ly Thai Tong, who dreamed that the Buddhist goddess of mercy, Quan Am, handed him a baby son while seated on a lotus flower. He had no heir at the time; soon after, he married a peasant girl and had a son. In gratitude, he built the pagoda in the shape of a lotus blossom rising from the water, supported by a single pillar — meant to represent the lotus's stem.
What you'll see today
The current structure is a mid-20th-century reconstruction (the original was destroyed in 1954), but it's faithful to the design and still striking, particularly with the small pond and surrounding gardens. It's a quick stop — most people spend 10–15 minutes here, including photos.
