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.

The park is located in the north-eastern part of the Province of Varese, in the Italian region of Lombardy. It takes the name from the main geographic features located in the park, the five mountain peaks.
