Located east of modern Zangri town, Zangri Kharmar is the sacred meditation cave complex where Machik Labdrön (1055-1149) practiced, taught, and passed away. Built upon a red rock overlooking the Yarlung Tsangpo, it remains a vital pilgrimage site for the Chö lineage.

Located in northeastern Bhutan’s mountains, Druk Zangri Khangmar (« The Bhutanese Red Citadel of the Copper Mountain ») shelters a community of Chö practitioners founded in 1952 by Trülshik Rigdzin Lingpa, a direct student of Shuksep Lochen Chönyi Zangmo.
