The Eiffel Tower in Paris was closed on Monday as employees went on strike to protest claims female colleagues were told to stay out of sight during a visit by a Hindu religious group, drawing criticism from French politicians.

Around 100 members of the Bochasanwasi Akshar Purushottam Swaminarayan Sanstha (BAPS), a global Hindu organization headquartered in Ahmedabad, India, visited the landmark on Saturday.

BAPS describes itself as a “spiritual, volunteer-driven fellowship” dedicated to improving society through individual growth and promoting the Hindu values of faith, service and global harmony. The group inaugurated a new Hindu temple in Paris on Sunday.

Diane Davoine, a union representative for the Eiffel Tower staff, told reporters that during the visit, “women were asked to leave their places of work in order to place men there.”

“So that absolutely does not go down well with the employees, with women obviously, who are all humiliated by what happened, by the way some were treated,” she said.
