Gongsanseong Fortress, perched along the hills overlooking the Geumgang River in Gongju, South Korea, is a historic mountain fortress that once served as a royal palace and stronghold of the Baekje Kingdom during its later period. The fortress follows the natural contours of the landscape, blending seamlessly with the surrounding forested slopes. Originally built from earth and later reinforced with stone, Gongsanseong showcases both defensive ingenuity and architectural elegance. All photos created with the Nikon Z6 and either the 14-30mm f/4 or 24-70mm f/4 lens. Processed using Photoshop CC and either Nik Collection’s Color or Silver Efex Pro.
