Today, the Eiffel Tower, which continues to serve an important role in television and radio broadcasts, is considered an architectural wonder and attracts more visitors than any other paid tourist attraction worldwide. More than 7 million people visit this iconic tower every year. Since the tower's 1889 opening, 250 million people worldwide have enjoyed all the Eiffel Tower offers. And it has a lot to offer. The tower's three platforms are home to two restaurants, several buffets, a banquet hall, a champagne bar, and many unique gift shops. Educational tours of the tower are available for children and tourist groups. But one spot has fascinated many—the “secret” apartment.
