The Troll Wall (English) or Trollveggen (Norwegian) is part of the mountain massif Trolltindene in the Romsdalen valley in Rauma Municipality in Møre og Romsdal county, Norway. It is located to the south of the towns of Åndalsnes and Molde inside the Reinheimen National Park. The Troll Wall is the tallest vertical rock face in Europe, about 1,100 metres (3,600 ft) from its base to the summit of its highest point. At its steepest, the summit ridge overhangs the base of the wall by nearly 50 metres (160 ft). The Rauma River, the Rauma railway and the European Route E136 run just to the east of the wall.

Romsdalen is a valley in the western part of Norway. The 60-kilometre (37 mi) long valley runs through Rauma Municipality in Møre og Romsdal county and Lesja Municipality in Innlandet county. It is the valley of the Rauma river, from Old Norse word Raumsdalr which means Rauma valley. The traditional district of Romsdal, which makes up about one-third of Møre og Romsdal county, is named for the valley of Romsdalen. The main road E136 and the Rauma line runs along the valley floor.
