Chagri Monastery was the first monastery established in Bhutan by Zhabdrung Ngawang Namgyal in 1620 when he was about 27 years old. He spent several years in strict retreat in a cave at Chagri, which is the first hermitage in this place. Located on the slope of a rocky mountain not far from Tango, it serves as the main retreat center for the monks of Bhutan’s State Monk Body.
