Two Jangseung (장승) spirit posts stand guard outside the 'Korean Way of Life' exhibition at the National Folk Museum of Korea (국립민속박물관) in Gyeongbokgung Palace (경복궁), Seoul (서울).
The Jangseung is a wooden pole (though sometimes made of stone) with a face carved near the top. They would normally be placed near the edges of villages to mark the village boundary and frighten evil spirits away from the village. Villagers would also pray to them to prevent calamity and bring a bountiful harvest.
