Visitors to this park can step into the past on the "Monterey Walking Path of History" and view the site where Spanish explorers first landed in Monterey in 1602; see one of the nation's last remaining whalebone sidewalks; and walk the same streets that author Robert Louis Stevenson walked in 1879 as they explore this two-mile path and discover some of California's most historic homes, buildings, and gardens along the way. Monterey served as California's capital under Spanish, Mexican, and U.S. military rule. The U.S. flag was first officially raised in California here on July 7, 1846, bringing 600,000 square miles of land to the United States. Ten buildings, including the Custom House, the oldest government building in California, and several residences (now house museums with guided tours), are all part of the Path of History.
