This is a small and simple museum, showing various antique equipment used in science, such as antique microscopes, telescopes, thermometer, barometer, etc. It also houses the equipment used by Horace-Bénédict de Saussure (a Swiss geologist and meteorologist) to explore and map the Alps during the 18th century. Located just a few steps from Lake Geneva, this museum worths to visit if you walk along the Lake’s right bank. The old building has a beautiful interior and view to the lake from the 2nd floor. A downside of this one is that not all pictures/equipment have an English description.
