The Eiffel Tower closed to the public until further notice after a breakdown in negotiations over workers' contracts, Paralel.Az reports citing DW.

The strike was declared ahead of contract negotiations with the city of Paris, which owns the 134-year-old monument, an Eiffel Tower spokesperson said.

Union representatives did not immediately respond for comment, and it was unclear how long the strike would last.

Tourists can still access the glass-enclosed esplanade beneath the tower, but access to the 300 meter (984-foot) tall landmark itself is closed until further notice.

One of the world's most-visited sites, the Eiffel Tower is typically open 365 days a year and is expected to play a central role in the 2024 Paris Olympics.
