Shahr-e Rey is the oldest existing city in the province of Tehran, Iran. The city is estimated to be more than five thousand years old, and was built during the Median Empire. It was known in Classical times as Rhagae. Ray is richer than many other ancient cities in the number of its historical monuments, among which one might refer to the 3000-year-old Gebri castle, the 5000-year-old Cheshmeh Ali hill, the 1000-year-old Bibi Shahr Banoo tomb and Shah Abbasi caravansary. It has been home to pillars of science like Rhazes.
