Members of a special firefighter climbing unit and police negotiators eventually persuaded the man to surrender.

A Paris police official said the man was "under control and out of danger" on Monday night.

Managers said the tower would reopen on Tuesday morning as usual and promised to reimburse people with reserved tickets whose visits were thwarted.

Security agents spotted the man climbing up from the second floor in the early afternoon, triggering an operation to evacuate the 2,500 visitors on the monument including people dining on the second level.

The man eventually stopped his climb just below the third level, which is the highest level of the 324-meter tower, and stayed there.

His motives remain unclear and authorities have declined to identify him.

Hours into the sky-high incident, the man could be seen standing in the ironworks of Gustave Eiffel's 19th century monument. A rescuer dressed in red was nestled nearby, interacting with him.

Authorities wouldn't say how the trespasser managed to get past a stringent security system.

The tower's management company, called SETE, insisted such intrusions remain "very rare".

The tower, the tallest structure in Paris, is about the same height as an 81-story building.
