Seoul City said Monday a 690-meter-tall, 133-story multifunctional skyscraper will be constructed in Sangam-dong. Once built, it will be the second highest after the 800-meter-high Burj Dubai, which is under construction, by South Korean developer Samsung C&T. The construction will cost more than 3.3 trillion won ($2.37 billion), the city estimates. To raise funds, 23 local developers signed an MOU at a Seoul hotel Monday with Seoul Mayor Oh Se-hoon attending. "The landmark building will help make Seoul more attractive and become a new tourist attraction here," Oh said. The multifunctional building will have hotels, offices, department stores, convention centers and various recreational facilities including an aquarium and movie theaters.
