Up to just fifty years ago, the waters of Lake Tovel – in the Non Valley, in the province of Trento – used to turn red in the summer. People – who’ve come here at almost 2,000 meters of altitude since Antiquity – of course came up with a famous legend to explain the phenomenon.

They say the queen of Ragoli, Tresenga, refused the matrimonial pursuits of foreign sovereign Lavinio, who wished to expand his kingdom by incorporating her territory through marriage.
