The official title of the One Pillar Pagoda is Yanyou Temple, also known as the Lotus Pagoda, located on the southwest side of Ba Dinh Square. The temple is small, but it is very famous across the land. Its uniqueness lies in the fact that it stands on a pillar in the center of the lotus pond, meaning that a pure lotus blooms out of the bitter sea. There are a lot of local people who come here to offer incense wishes. Even the President Ho Chi Minh used to come from time to time.
