Regarded as one of Vietnam’s most iconic architectural treasures, the One Pillar Pagoda rises like a solitary lotus from the water. Built in 1049 AD by Emperor Lý Thái Tông and dedicated to Quan Âm, the Bodhisattva of Compassion, the shrine has long drawn worshippers seeking fertility, health and divine favour, its slender silhouette a silent witness to a millennium of faith and history.
