Kongsten Festning

On what was once called "Gallows Hill" stands the flower-festooned Kongsten Festning. Dating from 1685, it once served as a lookout and warning post for the troops at nearby Gamlebyen. Although it can get overrun on summer weekends, it's otherwise lonely and appealingly intact. It's fun to scramble around the turrets, embankments, walls and stockade, or just sit in the sun and soak up the quiet.
