Built in 1974, this 1,450-foot tall structure held the world record for the tallest building for more than 20 years. Today, it's the second tallest building in the United States and the thirteenth in the world.
The reason Willis Tower is so popular is because of its Skydeck, which allows you to step on a glass "balcony" and observe the city underneath you with nothing obstructing the view. Feel free to take as many pictures as you want, the view from the Skydeck is truly spectacular. The most popular times to visit are during sunset and at night.
Be prepared for a long wait in line, try to avoid this place during the weekend. Buying a ticket online is going to save you a lot of queue time, but you are still going to wait for the elevator up and down. You can get here by subway, station Quincy/Wells; brown, orange, pink and purple line.
Last entry 30 minutes prior to closing.
Children (3-11): $17
