The Eiffel Tower's lifts have ground to a halt as an industrial dispute over security and working conditions brought workers at the Paris monument out on strike.
Thousands of visitors hoping for views of the city's skyline were left grounded as many of the tower's 300 staff walked out over late-running maintenance work and pay disputes.
Union representatives said they had been complaining about mismanagement of repairs to the 324m wrought iron structure for years.
Renovation of the west lift was projected to last 18 months when work began in 2008 but the project remains unfinished and employees say facilities are insufficient for the daily flood of up to 30,000 visitors.
"It took them two years to build [the Eiffel Tower], and now it's taking more than five years for one lift," said one disgruntled employee, who declined to be quoted by name.
