Historic Band-e Darreh Dam

Band-e Darreh is located near the city of Birjand in South Khorasan Province and is regarded as one of the region's important historic dams. It dates from the late Zand period and the early Qajar period, and is known as one of the most distinctive examples of water and mountain engineering in the region. Band-e Darreh is listed on Iran's National Heritage List under registration number 4816. The dam stands 5 kilometers beyond the end of Modarres Street, in the Bagheran mountain range, and became known as "Band-e Darreh" (the "Valley Dam") because water passes through the upper and lower valleys.

This historic dam was built on the orders of Amir Shokat al-Molk in 1294 AH (lunar Hijri). Band-e Darreh has a crest about 31 meters long and 3 to 5 meters wide, and was built using materials such as brick, stone, lime mortar and sarooj (a traditional waterproof mortar). The dam was designed to make use of the rock grooves on the valley floor, which provide a suitable bed for the structure. Besides its historical importance, the area around the dam has mountain scenery and a pleasant setting for walks and easy hiking.

To reach Band-e Darreh from the center of Birjand, head toward Modarres Street or Pasdaran Street, then continue along the route until you reach the Bagheran mountain range; the dam lies about 5 kilometers beyond the end of Modarres Street. The best time to visit is autumn or early spring, when the weather is mild and conditions are better for walking or easy hiking. While visiting, it is very important to practice responsible tourism: please pick up your litter, refrain from uprooting plants or damaging the historic stonework, and stay on the marked paths so that both the nature and the cultural heritage of the area are preserved.
