English: I am at the observatory for N-Seoul Tower, about 350 meters over the city.

I have a good view of some modern-day developments on the southern side of Seoul, including the Olympic Stadium, Lotte World, and COEX. Closer to me are the luxury apartments and shopping areas of Apgujeong-dong. In any case, it's all Gangnam Style here.

I can also see Seongsu Bridge, which opened in 1979, and due to shoddy construction quality, collapsed during a morning rush hour in 1994, killing about 30. Its collapse was a warning to South Korea's construction industry, which had emphasized speed and efficiency over quality through the building boom of the industrial era. In the wake of the Seongsu Bridge collapse, all Seoul bridges were inspected, and a 13-year-old rail bridge was found so unsafe that it was demolished and rebuilt in 1997.

The 2007 collapse of I-35 bridge in Minneapolis-St. Paul, Minnesota, USA is often compared to the Seongsu Bridge collapse, though in case of the I-35, the culprit was lax maintenance.

Back to Seoul, another building collapse, Sampoong Department Store in 1995, was also attributed to shoddy construction, as well as the store management's cavalier attitude toward safety and maintenance; over 500 people were killed.
