Tangeh Savashi (or Tangeh Vashi) is a gorge and narrow mountain pass in the Alborz range. Located 15 kilometers west of Firouzkouh, the narrow gorge was created by a perennial stream which comes down from a series of waterfalls upstream.
Slightly lower, in a hilly area, the stream provided a patch of lush grazing land within the mountains. Until the 20th century the area was a royal hunting reserve, populated by various wildlife. Fath Ali Shah (1772 – 1834), Qajar Shah of Persia, maintained a hunting lodge there and to commemorate his hunts he ordered the carving of a relief in the mid way point of the pass. There are ruins of a Qajar guard tower at the top of one of entrances to the gorge.
Today, the relief is a popular tourist attraction and the location is also highly popular among trekking and hiking fans.
