Among thousands of famous architectural works of the Hanoi capital, One Pillar Pagoda is an extraordinary work. The One Pillar Pagoda was originally built by the Emperor Ly Thai Tong who ruled from 1028 to 1054. It is a symbolic work of Hanoi Capital. Built of wood on a single stone pillar, the pagoda is designed to resemble a lotus blossom, the symbol of purity, rising out of a sea of sorrow.
