Lopper, Mountain and archaeological site in Hergiswil, Switzerland
Lopper is a mountain with steep slopes dropping roughly 500 meters to Lake Lucerne and Lake Alpnach on both sides, reaching 961 meters in elevation. The mountain holds archaeological importance and is recognized as a cultural property of regional significance.
In 1848, the Swiss federation supported construction of the first road around Lopper to connect isolated mountain regions and create new passages through the mountains. Tunnel construction followed later in the 20th century, fundamentally changing how people could reach this area.
The chapel on the eastern slope was built between 1964 and 1965, reflecting the spiritual connection locals have with this mountain location. It stands as a quiet reminder of how people have made this place part of their daily lives.
The Lopper Tunnel, opened in 1984, cuts through the mountain and connects both sides, with access to the A8 motorway toward Sarnen and the Brünig Pass. Visitors should know that the steep slopes require good physical condition and proper footwear.
The waters around the mountain are home to diverse aquatic life including perch, pike, and eels, drawing divers to the spot. This underwater variety makes the lakes a fascinating place for diving activities.
