The Mojhaye Khoroushan water park was closed on Sunday evening, Fars news agency reported, quoting manager Mohammad Babaei. It said customers were “ignoring chastity and hijab” rules.
The closure of the park, one of the largest in the world, has left 1,000 employees facing an uncertain future, Mr Babaei said.
Scores of businesses have been closed in recent months as Tehran clamps down further on women’s freedom, already vastly curtailed under the decades-long rule of the regime.
Book shops, cafes and clothing stores have been forced to shut after orders from authorities, who have threatened action against businesses serving women without the hijab required since the Islamic Revolution in 1979.
