Even on the most luxurious island of Iran you can enjoy a visit to a cultural heritage dating back more than two millennia. Kish Island has been inhabited by Iranians since Achaemenid Empire and it is rich in history as it is in beauty.
Kariz-e Kish is a remaining of an ancient Qanat (aqueduct) that has turned into an underground city and museum for people to visit.
Iranians designed Qanat system as an adaptation to arid climate five to six thousand years ago before the Roman Aqueducts. It is a hydraulic water system consisting of multiple vertical wells along a gentle slope that filters and guides water toward the arid areas.
Kariz-e Kish or Kish Qanat was built 2500 years ago to supply drinking water for island inhabitants. It’s a massive series of tunnels (10,000 square meters) snaking in a sixteen meters depth in coral earth of island. To have a good functioning Qanat it must start from a high elevation going down gradually to the valleys. But Kish Island does not have high elevation areas and still its Qanat is one of the best functioning in Iran.
Another factor that gives Kariz a unique characteristic is being in a coral ground. The coral reef purifies water very well plus when you walk in this cool ancient underground city, the walls and ceiling are covered with 500-600 million-year old fossils of turtle, shells, and other species of the sea.
