Description
In the 1980s, a tunnel was built under the Aare in Olten with great effort. In this tunnel, the electricity, gas, water, and telecom lines were laid to be disaster-proof.
"Energy yesterday - today - tomorrow," under this motto, the "Energy Tunnel" under the Aare was developed for tours. Besides the exciting experience of crossing the Aare on dry feet, we offer you a journey through energy history.
Dive into the past of energy supply, experience the rapid progress of the last two centuries and the impact on energy consumption. Gain an overview of today's energy supply in Switzerland and let your mind be inspired by energy pioneers and their future plans.
