Established in 1967, built in the style of a traditional temple, the National Library houses many ancient Dzonghka and Tibetan texts. It has been planned as "a major scriptural repository and research facility dedicated to the preservation and promotion of the rich literary, cultural and religious heritage" of Bhutan. The building is very lavishly decorated and is said to represent the finest vibrant Bhutanese architecture. On the ground floor of this building, among the highly prized collections, there is a book reported to be the heaviest in the world, weighing , known as "Bhutan:a Visual Odyssey Across the Last Himalayan Kingdom ". Traditional books and historic manuscripts written in Tibetan style, on handmade paper bound between wooden flats and tied together are also preserved here. The library also houses an old printing press that was used for printing books and prayer flags. The library is also circumambulated by devotees as a mark of worship by the devout as it enshrines holy books and images of Bhutan's famous people such as the Zhabdrung, Namgyal, Pema Linga and Guru Rinpoche. Also on display here are a model of the Punakha Dzong and the Chorten architecture.
