The place gets its name from the historic Daga Trashiyangtse Dzong which was established in 1651 by Zhabdrung Ngawang Namgyel the first man to unify the Bhutan. This historic landmark still functions as the district administration center today.
One of the more interesting features of Dagana are the three stone Megaliths, known as “Sky Pillar Rock” (Do Namkhai Kaw), “The Rock of Ancient Steps” (Do Kelpai Genthey) and “The Frontier Sky Fortress” (Tha Namkhai Dzong). Legend has it that when Daga Trashiyangtse Dzong was being constructed, the megalith known as the Frontier Sky Fortress emitted telepathic messages to the builders stating that the Dzong would collapse if it was built any higher than it currently stands. Even today the golden cupola of the Dzong is said to be level with the tip of the megalith.
As in all Dzongkhags there are Buddhist temples and monasteries throughout the district. Two that elicit special mention are the Shathong Lhakhang (temple), founded by the Buddhist Master Dupthob (Siddhi) Shawa Ripa and the Nyindukha Lhakhang founded in the 18th century. Shawa Ripa is an ancient Buddhist Master that is said to have lived for over 900 years.
Two of the main crops cultivated in the region are Oranges and Rice. Agriculture is the main source of livelihood for the inhabitants of the Dzongkhag. The district is mainly inhabited by two major ethnic groups, the Ngalops and the Lhotshampas though in recent year’s people from other regions have migrated to the region. This has added to the cultural diversity of the region with the introduction of new festivals and traditions.
