World's largest indoor ferris wheel

This building contains the world's largest indoor ferris wheel. It opened to the public on May 18, 2012. The ferris wheel is named "Alem", which means "The Universe". It features 24 six-seat cabins.

According to the current wikipedia article, the height of the ferris wheel is in dispute, with reports of 47 meters (154 ft), 47.6 m (156 ft), and 57 m (187 ft). Even the Guinness World Record web page confuses the situation by claiming a height of 47.6 m and a diameter of 57 m.

The building also contains a bowling alley, movie theater, a restaurant, and a planetarium.
