🏰 Troldborg Ring

The Troldborg Ring is an Iron Age fortification in Vejle Municipality in Denmark, 13 km (8.1 mi) west of the city of Vejle. It is located at a natural spring on a high point overlooking the Vejle River Valley. The surrounding area is a steep ravine known as the Devil's Valley. The site consists of a raised area of about 1,700 m2 (18,000 ft2) surrounded by a circular rampart. One side is protected by a steep drop of 70 m (230 ft) to the valley floor, while the other side features a 0.5-metre-deep (1.6 ft), 2.5-metre-wide (8.2 ft) moat.
