About Northern Frontier
The Cadorna Line, officially the Northern Frontier, was the Italian defensive system on the northern border facing Switzerland, designed and built between 1899 and 1918. Its purpose was to protect the Po Valley and its main industrial centres from an attack by France, Germany or Austria-Hungary violating Swiss neutrality.
