Dzong comes from Tibetan rdzong (fortress, stronghold, citadel, castle), a word of ancient provenance in the Tibetan and Himalayan world. The root dzong appears in compound words throughout the region: Dzongkha (rdzong-kha, 'fortress language') is the national language of Bhutan, so named because it was the language of the dzong courts; the country of Bhutan itself is called Druk Yul (rdzogs-kyi yul, land of the thunder dragon) in Dzongkha, but its administrative centers are the dzongs. The word appears in the place names of dozens of settlements throughout the Himalayan region that were once governed from or protected by fortified structures: Shigatse (from gZhis-ka-rtse, 'the peak of the estate'), Gyantse (rGyal-rtse, 'the peak of the king'), Tashigang in Bhutan, Wangdue Phodrang. The dzong gave its name not just to a type of building but to a type of place — the administrative node of a mountain district, the point where political, ecclesiastical, and military power converged in a single structure on a commanding height.

The Bhutanese dzong tradition reached its fullest development under the great unifier Zhabdrung Ngawang Namgyal, who founded or rebuilt a network of dzongs across Bhutan between 1616 and 1651 that served as the administrative and ecclesiastical framework for a unified Bhutanese state. The dzong's architectural program expressed the fusion of functions it contained: a massive exterior wall and fortified gateway housing a central tower (utse), around which were arranged the monastic quarters, administrative halls, and the dratsang (tantric college) in a spatial hierarchy that encoded the relationship between secular authority and religious authority within a single compound. The dzongs were designed to be visible from great distances — placed on ridges, promontories, and confluences of rivers — so that their sight alone communicated the presence of the state's authority in the valley below.

The construction of Bhutanese dzongs followed principles that European fortress architecture reached independently: the site chosen for maximum defensive advantage (commanding height, natural features on at least one side, clear views in all directions), the walls sufficiently thick to withstand siege, the water supply internalized. But unlike European military architecture, which tended toward increasing specialization and abstraction (from castle to fortified city to abstract defensive system), the Bhutanese dzong retained its civic and religious functions through every period of its development. The dzong at Punakha — built in 1637 at the confluence of the Pho Chhu and Mo Chhu rivers — flooded repeatedly through the centuries, was damaged by fires and earthquakes, and was rebuilt and restored after each event; it is still the winter capital of the Bhutanese monastic body and the seat of the Je Khenpo (chief abbot of Bhutan).

Dzong entered English primarily through the writings of British political officers and the accounts of early European travelers to Bhutan and Tibet. The word appears in the reports of Ashley Eden, who made a political mission to Bhutan in 1864, and in the accounts of John Claude White, who served as the first Political Officer in Bhutan from 1905 to 1910. White's Sikhim and Bhutan (1909) describes the dzongs in considerable detail and brought both the buildings and the word to a British readership. As Bhutan opened to limited tourism from the 1970s onward, the dzongs became the most photographed architectural subjects in the country, and travel writing about Bhutan standardized dzong as the English term for these buildings. The annual Tsechu festivals held within dzong courtyards — when the great thangka paintings are displayed and masked dancers perform the sacred Cham dances — became defining images of Bhutanese culture in international media.
