It was officially opened to the public on May 18, 2012. The 95-meter (312 ft) tall structure has a 17-meter (56 ft) decorative spire on top and has six floors, each of which are 7 meters (23 ft) tall (four floors are above ground and two floors are below ground). A 57-meter (187 ft) diameter glass and white-steel casing on top of the building contains a Ferris wheel known as ‘Alem’, meaning ‘The Universe’. Alem was recognized by Guinness World Records as the world’s tallest Ferris wheel in an enclosed space at the time of the opening ceremony.
