Several battles were fought in this area. According to Ferdowsi's Shahnameh the town has existed since the Afrasiab period and was named for its builder, Sarakhs, son of Godarz, by Keykavus. The surrounding oasis has been inhabited since 2nd millennium BCE and Turkmen historians consider the city to have been founded in 507 BCE. Although this is considered to be a somewhat arbitrary choice of date, the section of the city called Sarahs that's now on the Turkmenistan side of the border, duly celebrated its 2500th anniversary in 1993. The Mongols plundered and destroyed Sarakhs in 1221 AD. In the Seljuk Era a famous school of architects was located in Old Sarakhs, and the region retains the tombs of three major 11th-century figures, two on the Turkmenistan side of today's border (those of Abul Fazl, and the 1089 Yarty Gumbez, mausoleum of Sheikh Ahmed Al Khady) and the impressive Tomb of Baba Loghman on the Iranian side. All were significantly rebuilt in the mid-19th century by the order of Naser al-Din Shah Qajar of the Qajar dynasty, who also rebuilt the current Iranian-side town . Industries and Mines
