San Carlos Cathedral is a unique historical monument and the oldest Catholic parish in the state of California, having remained active since the 18th century. Located in the heart of Monterey, this church is considered the oldest stone building in the state, making it a must-visit for all history enthusiasts of the USA.

The cathedral, erected in 1794, is a striking example of Spanish colonial architecture. Its majestic sandstone facade and authentic interior decor allow visitors to touch the era of early settlers and missionaries. The church is dedicated to Saint Charles Borromeo and long served as the spiritual center for the residents of Old Monterey.
In addition to its religious significance, San Carlos Cathedral is an important cultural site surrounded by an atmosphere of peace and tranquility. Together with the adjacent historic school from the late 19th century, it forms an architectural ensemble that carefully preserves the heritage of the Spanish period and the first steps of American statehood in the West.
