Unlike the earlier Dzongs, that are located in strategic positions, Mongar Dzong is also located majestically on a small gentle sloppy area just above the town which was built in late 1930s, is one of the very few Dzongs that were built very recently in the country. According to oral legend, a king named Karpo Dung invited an architect from Paro (Zochhen Bala) to build a fortress in the region. The architecture while surveying the land came across a white stone shaped like a bowl on a mound just above Kurichhu so called the place Zhongkar (white bowl), now known as Mongar, and on this spot stands the present dzong. Zhongar Dzong was demolished by a fire and a subsequent earthquake and was abandoned thereafter and its functions shifted to present-day Mongar. The present fortress consist all the aspect of traditional architecture and plays a functional role as the district administrative offices and the monastic body for Mongar district. The walls and the Ceilings of the Dzong boast murals and paintings of Buddha’s doctrines. The Utse of the Dzong consist two entrances that very from other Dzongs in the country. A four day long Tshechu is held at the courtyard of the Dzong in November every year.
