Gyeongbokgung Palace, the main royal palace of the Joseon Dynasty, is more than just a residence; it is a massive philosophical structure reflecting the principles of the universe and harmony with nature. Situated on an auspicious site according to Feng Shui, with Mount Baegak behind and Mount Mokmyeok (Namsan) in front, every building’s placement embodies the Yin-Yang and Five Elements. The rough stone courtyard (Bakseok) in front of Geunjeongjeon is a masterpiece of scientific design, angled slightly for natural drainage and intentionally rough to prevent glare from sunlight.
