Expo 2012 opened in the port city of Yeosu, South Korea on 12 May 2012. A "recognized" exposition by the BIE, it closed meeting its goal of 8 million visits.

Like most world's fairs, the international participants occupied the largest area: a large International Participants Pavilion that also includes a huge overhead video screen called the Expo Digital Gallery (EDG) over its central axis.

Other notable buildings on site are the Korean Pavilion, the Theme Pavilion, the Sky Tower, and the Aquarium.

Off-site, an Expo Town was built to house the workers during the exposition. These buildings will become housing now that the exposition has closed.
