Dochula Pass is a breath-taking mountain pass, in commemoration of Bhutanese soldiers who passed away in military operations for the country. Along the Dochula Pass, there are 108 memorial chortens (also known as stupas) called the 'Druk Wangyal Chortens' for each soldier's life lost in the war. The hills are also decorated with colourful religious flags in five colours to represent the natural elements: blue for the sky, red for fire, green for water, white for clouds, and yellow for earth. To the local Buddhist people, these flags are symbols of veneration and the inscriptions of prayers on each flag signals peace and prosperity for Bhutan.
