Gasa Dzong is one of the remotest Dzong in the Country. Gasa Dzong is located at an elevation of about 2800m. The Dzong was said to have been built by Zhabdrung Nawang Namgyal in the 1640s above the cave meditated by a Tibetan saint Terkhungpa. It has a great tutorial, cultural, and spiritual significance. Just below is the “la Tsho” literally meaning soul-lake. The lake is an important part of the history of the Dzong. Local belief has it that Gomo, the guardian of the Dzong emerged from this lake in the form of a snake and held bound the Dzong when Tibetans attacked the Dzong with firearms in the 16th century. The lake surrounding was developed and named Eto Meto Garden and was inaugurated by Honourable Agriculture Minister, Dr. Pema Jamtsho on June 2, 2012, to commemorate the Coronation Day of Fourth Druk Gyalpo, Jigme Singye Wangchuck. About four species of Rhododendron plants are currently being planted around the lake in addition to tree species such as Juniper, Cypress, Willow, Oak, and Magnolia. The lake is also for winter birds such as Black tailed crake and ducks in addition to resident fishes confined in the lake.
Every year visitors coming to the Dzong and local communities go around the lake to enjoy the scenery and movement of the fishes in the lake. With the increasing number of visitors and local population in Gasa, there is a need to extend and improve the area with proper landscaping so that the visitors can enjoy and appreciate the beauty and historical importance of the lake.
