Seoul is the largest city in South Korea as well as the political and economic capital. While few historical points of interest remain (most of the temples and palaces are reconstructions), much of Seoul’s infrastructure is exceptionally modern and clean. Skyscrapers and high rises abound. Seoul is truly vast – though the casual traveler can see most of the main sites in a few days, a dedicated traveler could spend weeks exploring all the alleyways and far-off neighborhoods.
