The Eiffel Tower was closed following a bomb threat on Friday but reopened two hours later, Reuters reported.
Authorities from a bomb disposal unit were sent to the major Parisian landmark following an anonymous phone call around 2 p.m. that caused the alert. After investigating, police found nothing and allowed the tower to be reopened at 4:10 p.m.
According to the The New York Times, tourists at the top had to take lifts and then walk down 700 steps to get out quickly. Witness accounts on Twitter provided photos of tourists lined up outside of the tower and noted that police had formed a barricade.
The tower received bomb threats "regularly" but only carry out full evacuations a few times per year, Reuters reported. Recently, France has been on high alert even since a North African extension of Al Qaeda threatened the country following an intervention in Mali.
The U.S. also released a travel alert last week after threats from Al Qaeda, which does not expire until Aug. 31.
Finished in 1889, the Eiffel Tower is the most-visited paid structure in the world. According to it's website, the tower receives 7 million visitors annually - 75 percent of which are foreign.
The famous tourist attraction was recently in the headlines after a second replica was produced in China. Not only can you visit the duplicate structure on the Las Vegas strip, you can also tour one in Zhejian Province, China.
China's replica is surrounded by Parisian-styled homes and stands at 108 meters tall.
