Although still commonly referred to as the Sears Tower, London-based insurance broker Willis Group Holdings, Ltd. obtained the naming rights to the building on July 16th 2009. Sears’ legacy as one of Chicago’s mail-order giants, however, goes back further than the construction of the Sears Tower in 1974. | Chicago Architecture Center | Facebook

Once finished, at 110 stories high, it held the title of the world's tallest building for 25 years! | Marcus Leshock | Facebook

On this day in 1973, the 110-story Sears Tower in Chicago reached 1,450 feet, making it the tallest building in the world. Times change. The building is now known as the Willis Tower. It is the twelfth-tallest building in the world. For more, check out Aerial America: Illinois. 🏙️ http://bit.ly/2z9pMee | Smithsonian Channel
