Gasa Dzong
Gasa Dzong, officially known as Gasa Tashi Thongmoen Dzong, is a remote 17th-century fortress and monastery situated at an elevation of 2,850 meters in the rugged northern high Himalayas of Gasa District, Bhutan. Constructed in 1648 by Tenzin Drukdra, the second Druk Desi, over a 13th-century meditation site established by Drubthob Terkungpa, the circular fortress served as a vital northern bulwark against Tibetan military incursions. Perched amidst perpetual mountain mists, Gasa Dzong is famous in Bhutanese folklore for its Guardian's Temple (Goenkhang), where wrathful protector deities are entombed. Visitors and monks report experiencing phantom drumbeats, disembodied footsteps on the timber catwalks, and intense thermal drops around the sealed shrine of Mahakala.
