Archbishop Carlo Borromeo continues to reside at Milan, where serious administrative problems confront him.

He has regularly visited his more than one thousand widely scattered parishes, which fall under the jurisdictions of King Philip II of Spain and also of Venice, Genoa, and Novara.

His heroic behavior during the plague of 1576–78 has won him much respect.

Borromeo has fostered clerical education by establishing seminaries and colleges at Milan and in the Italian cities of Inverigo and Celano.

Colleges for lay students also have been erected and entrusted to the Jesuits.

The archbishop's last undertaking is the opening of the college at Ascona, Switzerland, in 1584; he dies at home on November 3.
