Jakar Dzong
Jakar Dzong, officially known as Yuelay Namgyal Dzong ('Fortress of the Victory of the White Bird'), is a massive 16th-century fortress dramatically situated on a high ridge overlooking the Chamkhar Valley in Bumthang District, Bhutan. With a circumference exceeding 1,500 meters, it is widely considered the largest dzong in Bhutan. Built on the site where a roosting white bird signaled a favorable omen to Lama Ngagi Wangchuk in 1549, the fortress played a pivotal role in defending central Bhutan against Tibetan invasions. The dzong is famous for its fortified water tower and subterranean passageways, which are reportedly haunted by the spirits of ancient siege defenders, fallen Tibetan warriors, and mountain guardian entities.
