Gros Caillou
A 24-tonne Alpine boulder and the eastern lookout of the Croix-Rousse plateau.
This boulder got here long before any of the streets around it. The Gros Caillou is a 24-tonne block of quartzite, torn from the Alps near the Maurienne and Tarentaise valleys and carried about 200 kilometres by a glacier around 140,000 years ago. Workers hit it in 1890 while digging the tunnel for the Croix-Paquet funicular, the little ficelle that pulled people up the hill. The stone was so hard they could not break it, so they dug it out whole and set it on a pedestal here in 1891.
The esplanade around you stands where that funicular line used to end, and the view still runs east across the Rhône plain to the Bugey. On a clear day you can make out Mont Blanc. This was the top of the line, where the plateau began.
