The Eiffel Tower was designed by Maurice Koechlin and built by Gustave Eiffel's firm between 1887-1889. It is an iconic symbol of Paris made of iron that attracts millions of tourists each year, though some Parisians initially disapproved of its construction. While it is a popular tourist destination that offers scenic views of the city, it is also the site of around 400 reported suicides over the years.
