South Khorasan Province Essentials

South Khorasan Province features a landscape of arid deserts and strategic mountain peaks defined by centuries of defensive architecture and water engineering. The region is home to historic mud-brick fortifications like Birjand and Forg Castles, and the ancient Kurit Dam, once the world’s tallest. Visitors can explore the geological Hole Rock formation, the mineral-rich Ferdows Hot Springs, and the exceptionally clear skies of the Seh Qaleh astronomy site. This collection highlights the province's transition from the Sassanid and Ismaili eras to its modern significance for celestial observation.
