One of the oldest Fe mines in Arendal.
Located on a hillside with surrounding houses. The shaft opening is about 50 m long and 15-20 m wide. The length and depth of the mine are uncertain, but measured from the map it spans about 130 m in length and 40-45 m down to a wooden door at the hill-face. The door is easily spotted since it is located right beside one of the leading roads into Arendal. Up until recent times, the mine was filled with garbage, but several years ago large amounts of garbage were removed. There is a lot of evidence regarding the mining operations that went on, many openings have been walled in and dikes are present.
