Old Town, San Diego

Old Town is a neighborhood of San Diego, California. It contains 230 acres (93 ha) and is bounded by Interstate 8 on the north, Interstate 5 on the west, Mission Hills on the east and Bankers Hill on the south. It is the oldest settled area in San Diego and is the site of the first European settlement in present-day California. It contains Old Town San Diego State Historic Park and Presidio Park, both of which are listed on the National Register of Historic Places.

The San Diego Presidio and Mission San Diego de Alcalá were founded in 1769 by Gaspar de Portolá and Junípero Serra on a bluff at the western end of the San Diego River valley. The Presidio and Mission constituted the first Spanish settlement in Alta California, the present day state of California. After five years the Mission moved to a location several miles upriver, while the Presidio on its hill remained the primary settlement. In the 1820s the town of San Diego grew up at the base of the bluff, at the site commemorated by Old Town San Diego State Historic Park, while the Presidio fell into disrepair.
