Punakha Dzong, located in the old capital, is undoubtedly the most beautiful castle in Bhutan. Unfortunately, we are visiting in winter and have no chance to see the beautiful scenery of spring purple lilacs and the magnificent white walls of Zongbao, but Zongbao Inside and outside the clear river, dense vegetation, magnificent buildings... Especially the incomparably lush big Bodhi tree in the atrium, refreshed my awareness of the solemn Buddha. Punakka Fort is located at the intersection of the Mother River and the Father River in Bhutan. This rich and inclusive location also indicates that the Fort is a pivotal place in the history of Bhutan, which moved to Bhutan in the 1950s. In the past, it has always been the religious and political center of Bhutan. There are countless treasures and exquisite buildings in Zongbao, but the most mysterious room is the secret room where the body of Xia Zongfa is stored. It is not allowed to visit here. Only a few people can enter, such as the King and the Emperor, too.
