Band Darre Dam is a huge building of stone, brick and mortar of Sarooj which was built on the flood route in Bagheran Mountains. This dam is the most important historical site in Birjand. The dam formed small lakes that could be used as a vacation spot. The local people and the travelers come to this area to spend some good moments in nature in different times of the year. Moreover, there are marches and climbing rides in this area. The dam construction has been formed from grooves on the sedimentary floors of the river bed. In addition to the large diameter of the wall that increased its strength, the architect used two tricks to enhance the wall's strength. First the construction of two bays with a width of about 1.80 meters and a rise of about five meters, will increase the strength of the wall. These two trailers are located on both sides of the emergency evacuation channel. Another step is to increase the strength of the arc dam in the reservoir that is given to the wall. There is a historic castle beside the dam which is located above a mountain summit that you have to cross certain paths to get into it. You can experience a unique journey with Alaedin Travel.
