The philosophy of traditional Korean architecture lies in its exquisite harmony between nature and human design. Its greatest appeal is the bold simplicity that rejects colorful embellishments and delicate decorations. The National Museum of Korea embodies this philosophy by reinterpreting it in a contemporary context. The museum's design concept envisions a safe and peaceful fortress nestled between Namsan Mountain and Mirror Pond. This solid fortress symbolizes a secure and tranquil environment, creating a sense of separation from the outside world. The museum's structure features two prominent walls, with the height of the walls extending to the roof to enhance their solidity. This design not only emphasizes the fortress-like appearance but also allows natural light to penetrate deeply into each layer of the building.
