One is the Eiffel Tower, typically a bright beacon of light near the banks of the Seine River. The soaring tower remained dark Saturday night and is closed to visitors for an unknown amount of time.
"The Eiffel Tower is currently closed until further notice," reads a scrolling banner along the bottom of the Eiffel Tower's official website. "At the request of Paris Mayor Anne Hidalgo, the Eiffel Tower will remain in the dark tonight in mourning. Thank you for your understanding."
A national state of emergency and a three-day period of mourning have been declared in Paris. The mourning period, from Nov. 14 to 16, prohibits public gatherings, drones and fireworks in the city and surrounding area.
Paris's world-renowned art museums, including the Louvre, the Musée D'Orsay, and l'Orangerie have also been closed to visitors in the days following the attacks.
Disneyland Paris announced it would remain closed through Tuesday, Nov. 17.
"We mourn those lost to the horrific attacks in Paris," Euro Disney S.A.S. president Tom Wolber said in a statement on the theme park's website. "We pray for the injured and we hold them all in our hearts."
