Gasa Dzong, the Fortress that Defended Against Northern Invasions
Gasa Dzong, also known as Gasa Tashi Thongmon Dzong, is one of the 16 dzongs built by the Zhabdrung Ngawang Namgyal in Bhutan to commemorate the victories over the Tibetans in 1646. The Dzong was built on a hillock at an elevation of 2800 meters above the meditation cave of Drubthop Terkhungpa in Gasa Dzongkhag.
