The Dzong Named for a White Silk Scarf

Dagana Dzong — Built to Defend the Southern Frontier

Dagana Dzong was built in 1651 by Dronyer Druk Namgyel under the direct command of Zhabdrung Ngawang Namgyal — as part of his programme of fortifying Bhutan’s southern frontier against the lowland states of what is now Assam and West Bengal. Its position on a ridge overlooking the valley reflects this defensive purpose. The first Daga Penlop (governor) appointed to the fortress was Tenpa Thinley, who became the first in a line of governors that would hold Dagana’s southern approaches for the Bhutanese state.

The dzong’s formal name — Daga Trashiyangtse Dzong — reflects its origins. Its popular name Dagana derives from two sources: the guardian deity Jomo Darkala and the description Darkanang, meaning the Realm of White Prayer Flags, given by the great Buddhist master Dudjom Jigdrol Yeshey Dorji. The founding legend of the white silk scarf — that a scarf was used to mark the sacred site for the dzong’s construction — gives the district its most commonly used name.

Inside the dzong are three ancient megaliths: Do Namkhai Kaw (the sky pillar rock), Do Kelpai Genthey (the rock of ancient steps), and Tha Namkhai Dzong (the frontier sky fortress). Among the dzong’s sacred objects is a buffalo horn measuring 4 feet 5 inches, believed to have been discovered by the first Daga Penlop Tempa Thinley. The dzong has withstood several earthquakes and windstorms; the most severe occurred during the sixth Penlop Pekar Jungney, when the entire roof was blown away. It was renovated and consecrated by the 10th Chief Abbot, Je Tenzin Chogyal.

Dagana and the Duar War

The Duar War of 1864–65 — also called the Anglo-Bhutan War — was the culminating conflict of years of tension between Bhutan and British India over the Duars, the lowland plains immediately south of Bhutan’s southern border. Dagana district, positioned directly above these contested plains, was one of the key frontline districts. The war ended with the Treaty of Sinchula in November 1865, by which Bhutan ceded the 18 Duars permanently to British India. In exchange, Britain agreed to pay Bhutan an annual subsidy. The loss of the Duars was a significant diminishment of Bhutan’s territory, and the southern boundary of districts like Dagana was permanently redrawn.

This history is present in the landscape of Dagana today: the district occupies the transitional zone between the Himalayan foothills that remained Bhutanese and the plains that became British (and later Indian). Attending the Dagana Tshechu is to gather in a dzong whose defensive purpose was tested by this specific imperial confrontation.

Things to See Near Dagana

• Dagana Dzong interior — the megaliths, the buffalo horn, and the surviving sacred objects from the dzong’s 370-year history. The dzong serves as both administrative centre and monastic body residence.
• Phuntsholing — the main Bhutan–India border crossing, approximately 3 hours from Dagana. The border town is a fascinating study in Bhutanese–Indian cultural contact.
