Lotte World Tower (Korean: 롯데월드타워), is a 123-story, 555 m (1,821 ft) supertall skyscraper, located in Sincheon-dong, Songpa-gu, Seoul, South Korea. It is the sixth-tallest building in the world, the tallest in OECD countries, and also the first in South Korea to be over 100 stories tall.
It was the fifth-tallest in the world when completed in 2016, though it was surpassed by the 599 m (1,965 ft) supertall building, Ping An Finance Center in Shenzhen, China, which opened on March 28, 2017. "The Tower" opened to the public on April 3.[4] Haeundae LCT The Sharp in Busan is the second-tallest building in the country.[citation needed]
A "Sky Bridge Tour" is located on the roof of Lotte World Tower at 541 m (1,775 ft),[5] which is the total height of One World Trade Center, the tallest building in the United States.
History
After 13 years of planning and site preparation,[6] the tower gained final approval to start construction by the government in November 2010[6] and the first groundbreaking activities of piling and frame assembly were observed at the construction site in March 2012.
On December 31, 2015, the LED-pixels of the façade displayed the number "2016".[7]
On April 3, 2017, Lotte shot off fireworks to celebrate the tower's official opening.[8]
On January 1, 2018, Lotte shot off fireworks with a LED laser show for seven minutes to celebrate New Year's Day and the 2018 PyeongChang Winter Olympics.
Design
On March 17, 2016, before the final phase of external construction, the Diagrid lantern-shaped roof structure was completed. The roof structure was constructed with steel counterparts that are each 12 m (39 ft) and weigh 20 tons. The counterparts were made up of bent metal panels that are 6 cm (2.4 in) thick. The roof structure itself is 120 m (390 ft) high and covers floors 107–123. Approximately 3,000 tons of steel parts, a high-precision 64t tower crane and GPS alignment systems, as well as welding technicians, were used in the construction of the roof.
The roof structure is engineered to withstand its weight without reinforcing pillars, endure earthquakes up to a magnitude of 9 under the Richter magnitude scale, and winds up to 80 m/s (260 ft/s).
The exterior of pale-coloured glass draws inspiration from Korean ceramics and features accents of metal filigree.[9]

Incidents and accidents
Safety issues
In 2013 and 2014, three construction workers died during the construction of the tower, and an executive director of Lotte's construction arm was given a suspended sentence of eight months in prison in 2016 for his role in neglecting safety measures at the site.[13] In December 2014, the Seoul city government ordered the mall and cinema complex at the base of the tower, which opened before completion of the tower, to be closed for five months after water was found leaking from an internal aquarium. Independent engineers who assessed the building found that the issues bore little relation to the overall structural integrity of the building and the mall and cinema complex reopened in 2015.[14]
Illegal entries and climbing
In 2016, two men from Ukraine illegally climbed the under-construction Lotte World Tower via its stairs, and one of them free solo climbed up the crane to the top.[15][16] Following the climb, Lotte World Tower released posters with the photos of the two and banned them from the building.[17][18]
On June 12, 2023, a 24-year-old British man illegally climbed the tower without ropes from the ground. The building security discovered him on the 42nd floor at 192 m (630 ft) above ground at 7:50 am. While he was taking a break on the 72nd floor, the police stopped him on the 73rd floor at 313 m (1,027 ft) above ground by using a building maintenance unit at 8:47 am. After his arrest, he said that he had planned the climb for six months.[19]
