藏经楼，傣语称“宏坦”或“业坦”，其意思是经库，是保管和收藏经书的地方。藏经楼的功能，主要是收藏民间有价值的傣文贝叶经和棉纸经书，每年关门节里的赕坦期间，民间都会有许多各种内容的经书供奉给佛寺，再由有学问的僧侣比丘用三天时间诵读，然后挑选出有价值的经作，进行修整后刻写在贝叶书上，装订好收藏在楼中，择时进行传教。

The building for storing Buddhist scriptures or Sutras is called “Hong Tham” or “Ye Tham” in Dai language. These scriptures, which contain a comprehensive compendium of local culture, are recorded in palm leaves and mulberry paper books. For a particular festival held every year during the Buddhist Lent, local villagers will “order” new texts to be produced by monks and novices as an offering to the temple, and these books will then be read and chanted during several days. Once the festival is finished, villagers may choose a text especially valuable for its amelioration of the tradition, then put it in the Sutra Pavilion in order to help spread the Dharma when the time comes
