Two American tourists were found sleeping off a binge in the upper levels of the Eiffel Tower in Paris after dodging security the night before, reports Radio France Internationale.
Security guards roused the men in the early morning as they were making their rounds before the French landmark's 9am opening time, Eiffel Tower operator Sete said on Tuesday.
"They appear to have got stuck because of how drunk they were," Paris prosecutors told the French news agency AFP.
The two Americans had spent their night under the stars in a spot normally closed to the public between the tower's second and third levels, but did not pose any apparent threat, said Sete.
After paying for an entry ticket around 10.40pm on Sunday just before the attraction closed, the pair hopped security barriers while climbing down the stairs from the tower's top, a police source said.
