Sajik park is located about 1 km west of Gwanghwamun at the foot of Inwangsan. The park is built around the Sajik oltar, a sacred shrine of the Cheoson Dynasty. The park is a home to Tangun's Shrine, the statues of Yolgok, a famous Korean philosopher and his mother, and also one of the oldest archery ranges in Korea (Hwanghakjeong). Walking across this park and going up a long flight of stairs will take you to one of the hiking trails of Inwangsan.
