Seoul, the capital of South Korea, is a massive metropolis that combines modern skyscrapers, a state-of-the-art subway and pop culture with Buddhist temples, palaces and street markets. Major landmarks include the futuristic Dongdaemun Design Plaza, a curved convention hall with a rooftop park; Geongbokgung Palace, which once had over 7,000 rooms; and Jogyesa Temple, with ancient Japanese string trees and pines.
