A 45-year-old employee of Disneyland Paris died in the theme park’s Phantom Manor attraction on Saturday morning, before the park opened for the day.
The technician was believed to have been electrocuted while working on the attraction’s lighting.
The park remained closed Monday while the fatality was being investigated.
"We are truly saddened to learn of the passing of one of our Cast Members, and our hearts go out to his family and friends during this very difficult time," the resort said in a statement.
Disneyland Paris is one of Europe’s top tourist attractions, with 14.2 million visits in 2014.
The BBC reported that an employee died at the same Disneyland park in 2010 after he fell into the water inside the It’s a Small World attraction and became trapped under a boat.
A similar accident in 2013 had a happier ending; a 5-year-old boy was pulled to safety by his father after falling into the water on the park’s Pirates of the Caribbean ride and becoming trapped under the boat.
