I was once standing in the tower on top of Castle Montebello in Bellinzona, looking out at Castlegrande. There was a group of schoolchildren up there with me. As I listened to them speak, I heard some speaking German and some speaking Italian. After a bit I realized they were coming from the same kids, and I surmised it might be Romansh. Always sad to think of unique cultures disappearing into the ether of history.
