Yazd water museum was set up in 2000 in the wake of the first international conference on Aqueduct (qanat) in Yazd. The museum building has once been a merchant’s house built in 1929. Two Aqueduct are running beneath the museum at different levels, which are reachable through a special stairway called Payab. This museum has put on display a variety of water objects from qanat to water ownership documents. Some parts of the house structure represent some parts of water history in the region. For example the stairway to Qanat or a reservoir on the roof can show how water technologies and everyday life have been interwoven in the past. The museum is one of the best tourist destinations in Yazd, which receive hundreds of visitors every day.
