Punakha Adventure Tours
In 1907, Punakha Dzong was the site of the coronation of Ugyen Wangchuck as the first King of Bhutan. Three years later, a treaty was signed at Punankha whereby the British agreed not to interfere in Bhutanese internal affairs and Bhutan allowed Britain to direct its foreign affairs. In 1987, the dzong was partially destroyed by fire.
Due to its location at the confluence of the Pho Chhu and Mo Chhu rivers in the Punakha-Wangdue valley, the dzong is vulnerable to flash flooding caused by glacier lakes (GLOF). According to a recent report, flash flood damage to Punakha Dzong occurred in 1957, 1960 and 1994. Currently (March 2010) work is in progress to protect the dzong from future flood damage by deepening the river channels and raising the embankments using four large steam shovels.
A covered wooden cantilever bridge crossing the Mo Chhu river was built together with the Dzong in the 17th century. This bridge was washed away by a flash flood in 1957 or 1958. In 2006 work started on a new covered wooden cantilever bridge of traditional construction with a free span of 55 meters which was completed in 2008 with the help from the Germans.
