In the heart of the city of Trollhättan lies an amazing place called Gamle Dal'n—a picturesque natural and historical landscape stretching along the legendary waterfalls on the Göta älv river. This is a space where the rugged beauty of Scandinavian nature meets the grand engineering heritage of Sweden.

This location gained fame due to its rapids and rocky islets. According to local legends, the shapes of the stones here reminded residents of a "troll's cap," which gave the entire city its name. For centuries, Gamle Dal'n played a key role in the life of the region: it was here that natural barriers dictated trade conditions and required incredible human ingenuity to master the waterways.
Today, the area is part of the massive Trollhätte Canal system. Visitors come here to see how turbulent streams of water carve their way through granite banks and to appreciate the scale of the ancient locks that transformed a once-wild river into a vital transport artery connecting Lake Vänern with the North Sea.
