Sundial frescoed in a niche carved into the wall. The dial was conceived as if it were a window to the sky, with a frame bearing the numbering of the hours, beyond which the clouds and the sky can be seen. The colors of the fresco recall the same colors of the exposed stones that make up the facade, the motto “Panta rei” written on the front of the sundial, whose view dominates the valley below up to a beautiful pre-Alpine lake, invites contemplation and peace , from his point of view he observes the passing of the clouds, the changing of the seasons and the flow of time. The dial shows the true solar time of the place.
