Shahrud (or Shahrood) is situated in the mid-eastern portion of Semnan province. To the south it is in the neighborhood of Khorassan province and Esfahan province and to the north lies Golestan province. In its northern section are the Alborz Mountain Ranges, and to the south is the Salt Desert. Its center is the city of Shahrood which is 400 km. from Tehran. The Taash river flows through this city, ending at the desert region. In the mountainous region it experiences cold weather, but in other areas it is relatively moderate. The city of Shahrood does not have an ancient background.
In the times of Fathali Shah Qajar it comprised of two ancient castles and a small meadow by the name of 'Shabdari'. But the surrounding areas named as, Biarjand, Miami and Bastam have an older history. Bastam is located 6 km. north of Shahrood, and according to narratives has been constructed during the reign of 'Khosrow Parviz' and yet another theory states it to be from the times of Shahpour Sassanide II (310 - 379 AD.). Naser Khosrow Qobadiani has mentioned Bastam as the center of the Gomess territory in the year 438 AH. After the Mongol invasion, Bastam was demolished and the current city of Shahrood which is located on the main road and railway net work of Tehran - Mashad gradually gained importance and took the place of the former city of Bastam.
