Cathedral of San Carlos Borromeo

The Cathedral of San Carlos Borromeo , also known as the Royal Presidio Chapel, is a Roman Catholic cathedral located in Monterey, California, United States. The cathedral is the oldest continuously operating parish and the oldest stone building in California. It was built in 1794 making it the oldest serving cathedral in the United States, along with St. Louis Cathedral in New Orleans, Louisiana. It is the only existing presidio chapel in California and the only existing building in the original Monterey Presidio.
The church was founded by the Franciscan Saint Junípero Serra as the chapel of Mission San Carlos Borromeo de Carmelo on June 3, 1770. Father Serra first established the original mission in Monterey at this location on June 3, 1770, near the native village of Tamo. However, Father Serra became engaged in a heated power struggle with Military Governor Pedro Fages, who was headquartered at the Presidio of Monterey and served as governor of Alta California between 1770 and 1774. Serra decided to move the mission away from the Presidio, and in May, 1771, the Spanish viceroy approved Serra's petition to relocate the mission to its current location near the mouth of the Carmel River and the present-day town of Carmel-by-the-Sea, California.
