Paro Dzongkhag (district) traces its Buddhist roots to the activities of Tibetan King Srongtsen Gampo in the 7th century, who is credited with building the Kyichu Temple located slightly north of town. In the 8th century, the Indian master Guru Rinpoche is believed to have undertaken ritual practice at the famous cliff-side Taktsang (Tiger's Den) Monastery, which remains a major pilgrimage site. In addition to the country's only international airport, Paro is also home to a regional hospital, the Paro College of Education, the National Museum of Bhutan, and the Wangsel Institute, which educates deaf children.
