Sebino Orientale
The eastern part of Lake Iseo, with the towns of Sulzano, Sale Marasino and Marone, up to Toline, a hamlet of Pisogne, was the site of one of the most daring feats of engineering for the time when the railway line was built The series of tunnels allowing trains to run through it, as clearly illustrated by the photos of its construction, demonstrate the difficulties encountered even in the planning of such an undertaking, and it should be noted that, with the exception of superficial conservation work, the structures have remained the same ever since.
