History of Monterey

The city was originally the only port of entry for all taxable goods in California. All shipments into California by sea were required to go through the Custom House, the oldest governmental building in the state and California's Historic Landmark Number One. Built in three phases, the Spanish began construction of the Custom House in 1814, the Mexican government completed the center section in 1827, and the United States government finished the lower end in 1846.

California period

Monterey was also the site of the July 7, 1846, Battle of Monterey during the Mexican-American War. It was on this date that John D. Sloat, Commodore in the United States Navy, raised the U.S. flag over the Monterey Custom House and claimed California for the United States.

In addition, many historic "firsts" occurred in Monterey. These include California's first theatre, brick house, publicly funded school, public building, public library, and printing press, which printed The Californian, California's first newspaper. Larkin House, one of Monterey State Historic Park’s National Historic Landmarks, built in the Mexican period by Thomas Oliver Larkin, is an early example of Monterey Colonial architecture. The old Custom House, the historic district and the Royal Presidio Chapel are also National Historic Landmarks. The Cooper-Molera Adobe is a National Trust Historic Site Colton Hall, built in 1849 by Walter Colton and was originally both a public school and government meeting place. It also hosted California's first constitutional convention. Today it houses a museum, while adjacent buildings serve as the seat of local government. The Monterey post office opened in 1849
