About Our Parish
Our Founding
The Royal Presidio Chapel of San Carlos Borromeo, also known as San Carlos Cathedral, is the oldest building in Monterey and the only remaining original chapel of the four Spanish Presidios that once existed in California. It is the longest continuously active church in California, established on June 3, 1770 when Father Junípero Serra said the first Mass under what became known as the Vizcaíno-Serra Oak.
