Qanats were underground channels built in ancient Persia to transport water from mountains to dry plains. This technology exemplifies early ingenuity in environmental adaptation.

Construction and Design

Qanats gently slope downward to carry water over long distances without pumps. Vertical shafts provided ventilation and maintenance access.

Importance to Society

Qanats supported agriculture, settlements, and trade in arid regions. They allowed Persian cities to thrive despite harsh climates and inspired similar systems across the Middle East and North Africa.

Legacy

Many qanats are still in use today, highlighting ancient engineering that combined sustainability with practical necessity.
