The town of Trongsa is situated on a steep ridge and offers spectacular views of the deep valleys surrounding it. The various hotels, guesthouses and restaurants all offer stunning views from their balconies. Trongsa Dzong is easily visible from anywhere in town and is always an impressive sight as it is situated atop a steep ridge that drops off into the clouds on its south side.
The Trongsa Dzong, which was built in 1644, used to be the seat of power of the Wangchuck dynasty before they became rulers of Bhutan in 1907. Traditionally, the King of Bhutan first becomes the Trongsa Penlop (governor) before being named the Crown Prince and eventually the King. Built on a mountain spur high above the gorges of the Mangde Chhu, the dzong controlled east-west trade for centuries. Trongsa also boasts an impressive museum. The watchtower of Trongsa has been converted into a museum dedicated to the Wangchuck dynasty and is a good place to learn about the history of the kingdom.
A five-day festival known as the Trongsa tsechu is held in the northern courtyard during December or January. Every monastery in Bhutan observes this festival, which celebrates the arrival of Guru Rimpoche to Bhutan in the 8th century, a mark of triumph of Buddhism over evil. It is held in spring and autumn seasons according to the Bhutanese calendar.
