Thien Mu Pagoda (namely Heaven Fairy Lady Pagoda), also known as Linh Mu Pagoda, is one of the most fascinating and ancient pagoda in Hue city. It is situated on Ha Khe hill, on the north bank of the Perfume River, in Huong Long village, 5 kilometers from Hue city, which is easy to reach from the city center. The name of the pagoda derives from a special legend. Long time ago, an old woman appeared on the hill where the pagoda stands today, telling local people that a Lord would come and build a Buddhist pagoda for the country's prosperity. Lord Nguyen Hoang therefore ordered the construction of the pagoda the "Heaven Fairy Lady" or Thiên Mụ in Vietnamese (also called Linh Mụ). Thanks to such a mysterious history, the pagoda has attracted a great number of tourists from both inside and outside of the nation to come and explore the legend themselves. The beautiful pagoda was built in 1601. Later on, several kings of the Nguyen Dynasty such as Gia Long, Minh Mang, Thieu Tri and Thanh Thai, all had the pagoda restored. At this very initial time, Hoang was the governor of the province of Thuan Hoa (now known as Hue), yet, started ruling his independent state in central Vietnam. According to the royal annals, Hoang was on a sightseeing trip and holiday to contemplate the seas and mountains of the local area when he passed by the hill, which is now the site of the Thien Mu Pagoda. On hearing the mentioned local legend, he had the pagoda constructed. The initial temple was in a very simple form of construction, but as time went by, it has been redeveloped and expanded with more intricate features. 1. Where is Thien Mu Pagoda located? 2.
