Spanish Road
The initial route of the Spanish Road ran northwest from the Duchy of Milan through the Duchy of Savoy, a Spanish ally, to the Spanish Franche-Comté, and from there due north through the Duchy of Lorraine, another Spanish ally, to Luxembourg in the Spanish Netherlands. This was the path along which Alba's forces marched in 1567, and Spanish forces continued to use it without significant interruption for the next thirty years.
