The door into the Punakha Dzong

Large volumes of timber were extracted and seasoned, including the spectacular giant cypress logs for special features like the solid kachen (pillars), dung (beam), cham (joist), and roof posts. Rocks were ferried to the site where masons chipped them into fine blocks. Metal workers shaped copper, brass, and iron into structural and artistic products. Sculptors molded dozens of religious images of all sizes to be installed in the Lhakhangs.
The construction of the Punakha Dzong greatly contributed to the revival of the 13 traditional arts of the zorig chusum. Artisans from all parts of the country were called on to hone their skills and a new generation of Bhutanese craftsmen was trained in the traditional skills and arts of the zorig chusum, under the supervision of the best craftsmen in the country.
