Expo 2012

Your ship is docked inside a World's Fair. The cruise berth, the terminal, the twin towers by the car park and the ring in the water were all built for Expo 2012 Yeosu. It ran from 12 May to 12 August 2012. The theme was "The Living Ocean and Coast". It was Korea's second world exposition, after Daejeon in 1993.

The numbers

The organisers set a target of eight million visitors and reached it on the final weekend. The official count was 8,203,956. The pace was uneven. In June about 50,000 people a day came through the gates. In July, when school holidays began, the number doubled. In the last four days it ran to 270,000 a day. Foreign visitors were about 400,000 against a hope of 550,000. The Expo cost ₩2.1 trillion, and ticket income came in at about two-thirds of forecast.

103 countries and eight international organisations took part on a 1.74-million-square-metre site along the water. The mascots were two plankton. The aquarium, now run by Hanwha, was the largest in Korea, with 34,000 animals of 281 species.

The Big-O

The centrepiece was the Big-O, a steel ring standing in the sea with a stage in front of it. At night it became a screen. Fountains with 345 nozzles threw seawater more than 70 metres into the air and projectors painted holograms on the falling water. The show was designed by the French firm ECA2 with the fountain specialists WET. It ran once a night from Sunday to Thursday and twice on Fridays and Saturdays.

The ring is still there. The night show continues in the warmer months with separate tickets. Whether it runs on a given evening is not published far ahead; the 2026 schedule had not appeared when this was written.

Two silos and the loudest organ

Before the Expo this was a working port, and the tallest things on it were two cement silos. The organisers kept them. They became the Sky Tower, 67 metres high, with an external lift to an observation deck. A desalination plant inside turned seawater into drinking water for the site.

Wrapped round the silos was a pipe organ, Vox Maris, the voice of the sea, built by the German firm Hey Orgelbau. Eighty pipes, the longest ten metres, played from a wireless console. You will read that it is the world's largest pipe organ. It is not; it holds the record as the loudest. Tested in Urspringen, Germany, on 21 October 2011 before shipping, it produced 138.4 decibels and could be heard more than six kilometres away. During the Expo it opened and closed each day and played a tune from every participating country, with "Arirang" the one everybody remembers.

Eighty pipes, 138 decibels, six kilometres: the loudest organ in the world, not the largest.

The organ was switched off after the Expo. The tower was remodelled with a media-art room and a water curtain and reopened on 25 March 2025, open 10:00 to 22:00 all year. It is three minutes on foot from the terminal's arrival hall.

The train that came early

The Expo's most lasting gift was a railway. Yeosu sits at the end of the Jeolla line. In 2011 the line from Iksan was double-tracked and electrified at a cost of about ₩1.7 trillion. The work finished two years ahead of schedule so that high-speed KTX trains could reach the site. President Lee Myung-bak marked the completion in Yeosu on 5 October 2011. Seoul to Yeosu fell from 5 hours 13 minutes to about 3 hours 30 minutes. The station, Yeosu Expo, opens straight onto the Expo grounds and is about ten minutes on foot from the cruise terminal. Seoul is still too far for a port day.

What the port got

Cargo handling moved to Gwangyang after the fair, and the Expo quay inside the north breakwater became Yeosu's cruise berth. It is one berth, 500 metres long and 11 metres deep. The port authority rates it for 150,000 gross tons, the tourism organisation for 170,000. The Expo passenger terminal handles immigration. The largest ship to use it so far was Spectrum of the Seas, at 169,379 tons, in May 2026.

The rest of the site did less well. Most exhibition halls were demolished. The International Pavilion, with 132,635 square metres of floor, was kept and is mostly empty; the Theme Pavilion is locked. The American pavilion became a hotel after five years dark. Ownership passed from the Expo foundation to the Yeosu Gwangyang Port Authority in 2023. The authority has a master plan for 2030 to 2040 and no settled schedule. A local hotel manager claims visits to Yeosu rose to 13 million a year after 2012. The tourism boom is visible in any case.

The 2026 Islands Expo

Yeosu is trying again, on a smaller scale. The 2026 Yeosu World Islands Expo runs from 5 September to 4 November 2026 under the theme "Islands, Connecting the Sea and the Future". The main venue is the Jinmo district on Dolsan island, with eight themed halls, and secondary venues on the islands of Gaedo and Geumodo. The old Expo site beside your ship hosts the forums. Thirty overseas regional governments and three international organisations signed up. The opening ceremony drew about 5,000 people. The October 2026 cruise calls fall inside it, which means crowds on Dolsan and on the cable car.
