This gallery shows some images published in the book
"La vita e l'opera di Bartolomeo Borelli, ingegnere"
They refer to the most important places where Borelli lived:
Pieve di Teco, Susa valley and Bardonecchia in particular,
where he lived 14 years and where he built the Frejus railway gallery.
At last, Borghetto Castle (Savona), where he spent last years of his life.
Images have been shown during an exhibition held at Pieve di Teco
